Make a tornado in a jar!10/05/2018

Make a tornado in a jar – That’s right, get in a spin and create your own mini natural disaster using some household items and a bit of glitter.

You will need:tornado experiment

1 x jar with a lid

Duct tape


Washing up liquid




  • Fill the jar 3/4 full with water.
  • Add in a few drops of washing up liquid and a couple of pinches of glitter.
  • Put the lid on tightly and carefully turn the jar upside down over the sink to make sure it does not leak. Use duct tape to secure the cap if required.
  • Keeping the jar upside down start to spin it in a circular motion. After a few spins stop and take a look…. You should be able to see your mini tornado begin to form but if not, don’t worry as it can take a couple of tries!

The Science Bit…

By spinning your jar in a circular motion you are creating a centripetal force which causes a mini vortex to form – This is your tornado.

Round and round…

This is the part where you can go and find out some fun facts about vortexes to impress your friends and family.

Tornados are natural disasters which are air vortexes. In the USA there is an area nicknamed “Tornado Alley” due to the amount of tornados that pass through the area.

Can you find out how big the biggest recorded tornado was? You will be amazed!

Other than tornados, where else can vortexes be found in nature? Do a quick search on the internet, you may find some cool pictures, facts and videos!!

FunScience Hint: Search ‘Fire Whirl’ on google.

You will need…

  • One egg
  • Bottle of white vinegar
  • Container big enough for your egg



  • Place your egg in your container and carefully pour in some of the white vinegar until the egg is covered.
  • Put the container somewhere safe and leave it alone for 48 hours.
  • Once the time is up, remove the egg carefully. What has happened?

The Science Bit:

Vinegar is acidic and the shell of the egg is made of calcium carbonate, when combined there is a chemical reaction in which the vinegar eats away at the eggshell, but leaves the membrane so you end up with a naked egg!


Experiment even more:

This experiment takes a bit of time, but there is lots you can do to keep you occupied.

For example, make a diary, take photos and keep a record of what happens to the egg from start to finish.

  • Did the egg change shape, size or colour?
  • What was the texture of the egg like after 24 hours?
  • What happens if you leave it for a whole week?
  • What did you notice about the shell when it was in the vinegar?
  • Shine a torch through the egg, what does it look like?


Floating Egg Science Experiment03/02/2016

The floating egg science experiment is simple and easy to do. Find out how to make an egg float using items hanging around in the kitchen cupboards.

You will need:Floating Egg Science Experiment

3 x Eggs

3 x Tall drinking glasses

1 x Jug of water

Table Salt

Measuring spoon



  • Half fill each glass with water.
  • Leave the first glass of water as it is. Put 2 tablespoons of salt in the second glass and 4tbsp in the third glass.
  • Give the salty water a good stir.
  • Carefully lower each egg into each glass. What has happened to each egg?


The Science Bit…

That’s right! Whilst the egg in the glass of water containing no salt sinks to the bottom, the ones with salt in float! Infact, the one with more salt in is likely to be at the top of the glass, whilst the one with slightly less salt is floating about midway. But how? Density, that’s how! What exactly is density I hear you ask? Great question!!

DensitFloating Egg Science Experimenty refers to the amount of molecules that are taking up a specific area. Imagine two rooms, one has 20 people in, whereas the other has none and is empty. This means that one room has a higher density than the other.

But what if we now put 40 people now into the empty room?  The empty room has now become more dense than the room with 20 people as there are more bodies (or molecules) filling that space!


This explains our experiment, the water without salt in is the empty room and the egg is the full room. By adding salt into the water we are increasing the molecules in that area. If we add enough salt we have made the water denser than the egg and so the egg floats!!!

Cool stuff right?

Did you know…

Near Israel there is a lake called the Dead Sea which is contains so much salt that people travel from all over to float around in it. Do a quick search on google and see if there are anymore salt lakes in the world that are similar.

Experiment even more…

Now you have learnt all about density the fun really begins.

  • Put the egg in the water without salt first, then slowly poor salt into the cup and watch the egg rise!
  • Alter the volume of water, the amount of salt and use different objects.
  • Test what objects float without using any salt at all – Don’t forget to check with an adult first before putting household objects in water.






Fun Science’s 10 Top Tips For Organising Your Child’s Birthday Party17/02/2015

Fun Science has compiled a top 10 tips list for making your child’s birthday party the most fun ever! Read below to find out our way of creating an amazing party without the stress associated with kids parties.

1 – Plan ahead

Nothing new there, eh? We don’t just mean by a few weeks, we mean by a few months. But if that makes you think OCD party planner, think again! Putting aside a piece of paper or notepad and writing a few ideas down every time inspiration comes to you can save a lot of stress and panic in the long run. Also by using this method ideas are likely to be created more organically.

2 – Theme it

Rainbow, Pink&Purple, Fairies, Pirates, Fun Science etc. The list is almost infinite. What are your kids hobbies? What interests them? Base the party theme around something your child adores, and they are bound to adore the party. This also makes questions about what cake/decorations/costumes etc. to choose a lot easier.

3 – Make sure you know who is coming

Is there anything worse than getting an invitation to a party a day or 2 before it? The same rule applies to kids’ parties. Make invitations with your little ones in the same theme as the party and either send them or give them to their friends at school. Bear in mind that many schools will only hand out invitations in school if the whole class has been invited so if you are only inviting some children it may be worth handing the invitations directly to the parents in the playground. Ask parents to RSVP so you know how many to cater for, how many layers of pass-the-parcel are needed and how many goody bags to make up!

4 – Feed them

Party food is probably one of the best things about birthday parties. Or am I just greedy?! Either way you’ll need to make some! It is so much cheaper and healthier to make rather than buy, so try making in advance and freezing as you go. Cupcakes, sausage rolls, biscuits, pizza swirls and most cooked things can be made ahead of time and frozen. Cheese and pineapple sticks, fruit salad, sandwiches and the like can be prepped a few days in advance and assembled on the day. Have fun with the food, and try to make it exciting!

5 – Consider hiring an entertainer.

Kids entertainers are a great idea for adding an extra wow factor to birthday parties. As well as making your child and their guests feel really special, they can bring an extra element of expertise. There are plenty of entertainers out there including circus performers, magicians and even Lego parties! Fun Science offer a mixture of fun and affordable birthday packages, check them out here //

6 – Games

Party games are essential to any child’s party. It may seem tempting but try not to over-organise or cram too many in. Often children will get distracted and want to go and do their own thing after 4 or 5 games. Sitting down games are great to keep things in check, but kids can become easily bored, which is why it is important to mix it up. Pass-the-parcel, sardines, musical statues and pin the tail on the donkey are a good mixture of active, static and engaging games. You could also try some simple but fun, science experiments. For inspiration check out //

7 – Music!

You’ll need music for pass-the-parcel and other games so make sure you have a functioning music player with a good, kid friendly playlist all lined up. There is nothing worse then rushing around trying to find the right CD once all the kids are sat down and waiting.

8 – Accommodate grown-ups

You don’t want floods of parents leaving their little darlings with you do you? Encourage other parents to stay for the event, make-sure there is enough seating for everyone, tea and coffee and maybe some grown-up nibbles. This ensures you don’t have the extra responsibility of looking after all the kids and it’s a great way to expand your social group.

9 – Cake!

The moment everyone has been waiting for! Cake time. Make sure you have made it in advance and finished off the decorations the day before or the morning of the party (or make sure it gets delivered in time if ordering one). Have all the candles you need to hand, safety matches, a clean, sharp knife and enough little plates. Check nobody is missing before you start to sing and remember to take lots of photos!

10 – Goody bags and goodbyes

Having goody bags is a great idea, as it can be a friendly, subtle signal for when the party is over, and it will keep the guests happy and excited, instead of throwing tantrums when it’s time to go. Fun Science offer party bags from just £2 each, and with all the great bits and bobs inside them you couldn’t make them yourself for less. Find them at //

What we have been up to – Summer 201316/09/2013

This summer has been a whirlwind of parties, holiday events and even a graduation! Read on to find out exactly what we have been doing and how Fun Science has been contributing to the local community.

Summer community events

Fun Science tries to help out local charities and community organisations by running workshops and activities for free or at a heavily discounted price whenever possible. This summer we spent a day running sessions for 150 girls aged 11-18 at a Guiding Event in Huish Woods, Taunton, Somerset. The girls were all given the opportunity to make their own rockets, raise their hair on our Van de Graff generator and learn a little about their own bodies with spirometers, lung capacity bags and blood pressure monitors. The following quote from one of the Guides (all of whom had been working their way around various activities throughout the day) summed up exactly what we at Fun Science are always trying to achieve.

“I was looking forward to the Fun Science least of all because Science is boring but it has been my favorite thing out of the whole day!” – Guide aged 14.

Fun Science were also very lucky to receive funding to work with some of the youngters who have recently started living on the brand new Wyndham Park estate in Yeovil and so Chemical Cress came along to do a couple of outdoor science sessions including rocket launches, illusions and chemical reactions. The primary aim of this event was to give the children on the estate, many of whom have moved to England from various European countries, a chance to get to know each other and to make friends with others in a similar situation to themselves. Fun Science helped to get the children interacting with each other through a range of activities whilst also getting them excited about science – the Mentos and diet coke experiment was a big hit!

This summer, Cressida Bullock, the owner of Fun Science and the leader of many of the company’s events, graduated from Bath Spa University with a 1st Class Honours degree in Biology. This was a very exciting day and you can see Cressida below, dressed in her graduation robes with a very big scroll!

Lots of new scientists join our team

With the increasing popularity of our holiday events it became necessary to increase the size of our team at these events. We were very happy to welcome back some familiar faces and have also taken on some new members of staff for holiday events. Pictured below are Krypton Katie, Mercury Mali, Helium Hattie and Chemical Cress after working extremely hard at our three summer fun days in Bath.

We have also been very excited to take on a new employee to cope with an ever increasing demand for Fun Science birthday parties. Our new party entertainer Hydrogen Hana has already received some fantastic feedback and, following extensive training, received the following review after her very first party!

“Could you pass on to Hana that she was very good and the children all loved it, I didn’t know at the time it was her first time, and I wouldn’t have guessed. (my husband told me later, she had told him) she was prompt, confident at talking to the children, and as my 3 year old said ‘the science lady was very friendly’ !  They all loved making the slime, getting certificates with their science names on and the experiments she did with mixing the household ‘chemicals’ . Particularly the green stuff that foamed out of the top. My son was delighted at being at the front helping, that was just what he wanted as birthday boy”

How to choose a children’s entertainer and what questions to ask21/07/2012

Children’s entertainers can be a fantastic addition to your child’s birthday party as they provide something a little bit different whilst taking the pressure off you as a parent. When it comes to choosing the entertainment for your child’s birthday party, it’s important to get it right. Luckily, as entertainers ourselves, we at Fun Science know some of the top tips for choosing the entertainment for your child’s party!

1) Find something your child is interested in – So maybe your child likes dinosaurs, princesses, science etc.. Try and find an entertainer that specialises in providing parties to suit your child’s interests. Children’s entertainment has progressed a long way from the times when every child had a juggler or a magician at their birthday party. Of course, there are many fantastic jugglers, clowns and magicians around and so if this is what your child is interested in then my all means book one, but don’t be afraid to look around for something a little bit different. 

2) Pick a recommended entertainer – Any good entertainment companies will have a section containing testimonials or comments from previous parties, however if they don’t then do not be afraid to ask for one. Also, many companies offering character entertainment may employ a number of staff to act as that character and some may be better than others. Make sure you ask for a review or reference of the specific person that will be leading your entertainment on the day. 

3) Shop around – Cheaper prices do not necessarily mean lower quality – As a company offering prices that undercut many other similar companies in the area, we often hear comments such as ‘we paid far more for her brothers party and it wasn’t nearly so fun!’. This is because a lower priced company does not necessarily mean that the quality is compromised, in fact it is far more likely to be indicative of the companies costs. For example, our parties are priced fairly low because we have very few overhead costs and prefer to use word-of-mouth advertising. 

4) Communicate with your entertainer – Tell them if you have any special requirements. Perhaps your child is particularly looking forward to seeing a particular magic trick or juggling routine that they saw at a friends party – be sure to let your entertainer know to avoid disappointment.The golden rule here is ‘just ask!’. At Fun Science we are always happy to do all we can to cater to size, age and theme requirements, but if we don’t know that there will only be 5 children or that your child has invited friends aged from 3-11 – we can’t prepare!

5) Make sure the entertainment will be age appropriate – Most entertainers will have age guidelines and it is generally best to stay within these. If they do not state a particular age, it is best to ask or to let them know the age of the attending children so that your party can be altered accordingly. However, that being said, you know your children best and if you think that a party that claims to be suitable for ages 6-11 would suit your 4 year old perfectly then remember the golden rule and ‘just ask’. Our parties are recommended for children aged 5-11 yet we have run many successful parties for children slightly younger or older whose parents have let us know their child’s age beforehand. 

6) Book a Fun Science birthday party! – Of course, this list wouldn’t be complete without a little shameless advertising! If your child is into science, our party packages are engaging, interesting and have received many fantastic reviews. We also cover most of Somerset and Wiltshire so have a look for yourself at //
