Our Chief Fab Scientist is turning 40 so we’re giving away £40 of freebies with any parties booked this week!

This birthday thing has gone to her head so get in there quick and snap up a great deal! Book your child’s party today and you can choose from a super-cool dry ice demonstration or 10 standard party bags absolutely free.

What do I have to do?

All you need to do to take advantage of this offer is contact us today to enquire about your next party. As long as we get your enquiry by midnight Sunday 7th July, you’ll have a week to make your mind up. If you decide to go ahead and book, we’ll need your deposit by midnight Sunday 14th July to lock in the deal.

But my party is so far away, I can’t book a venue yet or know how many children we’ll invite!

Don’t worry, all you need to do for now is get the date in the diary and confirm your booking with a £50 deposit. We’re taking bookings right up to next summer. We’ll be in touch much nearer the time to finalise the details.

What is dry ice and why is this such a good deal?

Dry ice is frozen carbon dioxide and doesn’t behave like normal ice. Instead of melting to become a liquid and then evaporating, it skips the middle-man and sublimes from solid to gas. This means you can get some really cool effects as it makes pretty impressive clouds of fog! We use it to make pourable clouds, heaps of bubbles, ‘smoke’ rings, blow stuff up and wash our hair in a cloud. It is truly magical and always gets gasps of excitement from the children (and the grown-ups!). We charge for it separately as we have to order it in specially for each event…it is so good at subliming that it disappears in a day or two! But you can take advantage of this fantastic offer and get your dry ice demo completely free.

What’s in the party bags?

Our standard party bags contain a mini experiment kit, a test tube full of jelly beans, diffraction classes that make all lights look like rainbows and a few other science-fun things! The party bags are usually £4.50 each and you can get ten of them for free with this offer. You can order extras and upgrade to deluxe or Harry Potter themed bags if you like.

What do I need to know about Fab Science parties?

They are great fun and full of awesome experimenting! All your questions can be answered on our party page. For a quote to include travel to your location, everything you need for an unforgettable party and a Fab Scientist or two to lead all the fun, get in touch today. We even offer a Potty Potions party option for your young witch or wizard!

We’re so excited to announce that Fab Science camps have been voted the Best Holiday Club in our region in the 2019 Hoop Awards!

Our team have run nearly 200 camps, been visited by thousands of young scientists and hopefully inspired many of them to get stuck into science. We always aim to make each camp 100% fun, while being educational, interesting and inspiring the children to learn more. All of our Fab Scientists are passionate about including every child and encouraging exploration and experimentation in every activity. We know that we make every event the best it can be so we’re incredibly proud that this has been recognised in the Hoop Awards.

We’d like to say a huge THANK YOU to all of our lovely customers who voted for us in this award and who continue to support our camps and events.



All living things* have DNA; animals, plants, fungi, even teeny tiny bacteria. It’s what makes us who we are. At ‘All About Me’ camps, we made models of DNA and also had a look at some real DNA that we extracted from strawberries. There were lots of requests for instructions on how to do this at home so here is the recipe!

You need:

  • Two strawberries
  • Surgical spirit (available in any chemist)
  • Washing up liquid
  • Table salt
  • Ziplock bag (use pestle and mortar to avoid using plastic bag)
  • Plastic cups or beakers
  • Small glass (shot glass would be ideal)
  • Small sieve or tea strainer
  • Tweezers or cocktail sticks


What to do:

  1. Put the surgical spirit in the freezer at least an hour before you start. Leave it there until step 8.
  2. Remove the leaves from the strawberries and put the fruits in the bag.
  3. Mash the strawberries! This is the fun bit…don’t break the bag though. You can squash the strawberries in a pestle and mortar (or bowl and spoon!) instead to avoid plastic waste.
  4. To make the extraction mixture which will break open the cells and let the DNA escape: measure 90ml water into a beaker or cup, add a teaspoon of salt and two teaspoons of washing up liquid. Stir slowly…we want it mixed but not bubbly.
  5. Add 4 teaspoons of the extraction mixture to your bag of mashed up strawberries. Mix GENTLY.
  6. Sieve the strawberries into a clean beaker.
  7. Pour this into your small glass. The DNA is now free in the mixture instead of being stuck inside cells but it is VERY thin so we can’t see it.
  8. Carefully pour some cold surgical spirit on top of the strawberry liquid. You should see a cloudy white layer appear, this the DNA! The alcohol makes it clump together so you can see it. You can pull this out with tweezers or a cocktail stick to have a proper look.


*All cellular life on Earth has DNA. Some viruses have another molecule called RNA instead but it’s a bit of tricky question to decide if viruses are actually alive anyway. Of course, we don’t know if any lifeforms that may exist on other planets have DNA or something else entirely.

We’re super excited to launch our Awesome Engineering camps for February half term. We’ll be testing out different shapes and materials to find out how to make super strong structures…and testing them to destruction! Then we’ll all work as a team to make a MASSIVE pyramid. This will be over 4 metres high and we can all get inside it!

The camp is suitable for children aged 5-12. The children will be grouped with other kids of a similar age and our Fab Scientists are always ready to support them and encourage them to explore. If you are booking with friends, just let us know that you would like the children to be grouped together.

When and where?

Monday 18th February: Cambridge – Queen Edith School

Tuesday 19th February: Saffron Walden – R A Butler School

Wednesday 20th February: Bishop’s Stortford – Hillmead School

Thursday 21st February: Hertford – St Joseph’s in the Park School

Friday 22nd February: St Albans – Garden Fields School

All camps run 10am to 3pm, with a chance for parents to come and share the children’s discoveries at 2:50pm.

Any questions?

You can find out all about our camps on our main camps page. If there’s anything else that we can help with, please do get in touch, we’d love to hear from you!

Ready to book?

You can book and pay via our online booking system (click here). Camps cost £32 per day and we offer a discount for siblings booking together.

We look forward to seeing your awesome engineers at Awesome Engineering!

Giant tetrahedron
Here are our Fab Scientists inside the giant pyramid. Believe it or not, we fitted 30+ children inside (when we got out!).




Make your own Christmas gifts, with help from a little bit of science!

A chemical reaction that you can eat: honeycomb

All cooking is chemistry in action but my favourite edible experiment is honeycomb or cinder toffee. If you want to get all technical, this reaction is the thermal decomposition of sodium hydrogen carbonate to produce sodium carbonate, water and carbon dioxide gas. Basically, heat up baking soda and it gives off gas! If it is mixed up in some lovely gloopy melted sugar when this happens, you’ll get bubbly toffee which makes a great Christmas present for someone with a sweet tooth.

You will need: 200g caster sugar, 5tbsp golden syrup and 2tsp baking soda. Heat the sugar and syrup in a pan while stirring (this is definitely a grown up job!), when it is all melted and golden, remove from the heat and quickly stir in the baking soda. Watch as the chemical reaction happens and bubbles of carbon dioxide form in the toffee. Quickly pour onto a greased baking tray and wait for it to cool before testing out your tastebuds!

Fizzy bath bombs

These bath bombs don’t actually explode but they will fizz away when you put them in the bath. All the ingredients can be found in your kitchen/bathroom cabinet or can be bought in the supermarket (except citric acid which you can find in a chemist or homebrew section, I picked some up in Wilkos for 75p).

You will need:

Corn flour (2 tablespoons)

Citric acid (2 tablespoons)

Bicarbonate of soda (4 tablespoons)

Oil – coconut or olive are good (1 tablespoon)

Optional extras:

Food colouring

Fragranced oil/perfume (check it’s safe on skin)

A few dried flower petals (crushed)


What to do:

Mix the corn flour, citric acid and bicarbonate of soda together in a bowl (and flower petals if using). If you want to use fragrance and/or colouring add a few drops to the oil in a plastic cup. Then add the oil slowly to the dry ingredients, mixing in between. You may need add a bit more oil if it doesn’t form a paste (not too much though). When it’s nicely mixed, shape it into balls and leave them to dry on greaseproof paper. They’ll be fully dry in a couple of days then store them in an airtight tub. Pop the balls into cupcake cases and people will think that you have made lovely, thoughtful gifts, not just had fun with science!


What’s going on?

The bicarbonate of soda and citric acid will form a chemical reaction, making lots of carbon dioxide gas. This gas makes the fizzing and bubbles that you see when the bomb is dropped into water. The chemicals can’t react together when they are dry so the fun only starts in the bath!



We love to see you all enjoying science…that’s why we do science parties, camps and visit schools all year round! We like to see that ‘wow’ moment when kids see the awesomeness of science. However, experimenting shouldn’t stop when you leave a Fab Science event, that’s just the start! We’ve given you some ideas of activities you can try on our Home Science page and we know you have loads more ideas of your own. Please share them with us…and you could win a Fab Science goody bag!

You could take a photo or video of yourself trying out an experiment or visiting a science museum. You could send us a picture of something that you have created or an interesting find. You could even do an ‘elfie’ instead of a ‘selfie’ and get your elf doing experiments like Whizzy, the Fab Science Elf! Feel free to add captions or comments explaining what your selfie or elfie is all about.

We now have a Facebook group set up specially for sharing your science ideas, or tag @fab_science in your Instagram science selfies and use the hashtag #FabScienceSelfie.

To be in with a chance of winning, you’ll need to post your photos or videos by the end of December. If you prefer you can email them to selfie@fabscience.co.uk instead.

We can’t wait to see what you will think of!

Happy experimenting!

Terms and conditions:

  1. There will be one prize of a deluxe Fab Science goody bag and two runner up prizes of standard goody bags (shipping to UK addresses only).
  2. The Fab Science team will decide the winners based on creativity, fun, interest and scienciness (if it isn’t a word, it should be!).
  3. Any images or videos posted to the Fab Science Facebook group or using the #fabscience hashtag during this competition may be used by Fab Science for marketing purposes. Please make sure you have the consent of anyone in the photos (or parents/guardians) for them to be used in this way.
  4. Entries must be received by midnight on Monday 31st December 2018.
  5. You may enter as many times as you like!



Eat your greens! No more sweets! Drink your milk! No fizzy drinks! Parents are always telling us what to eat but why? Investigate food packaging to find out which foods contain lots of sugar or plenty of good stuff like calcium and fibre. If you have access to the internet, you can experiment with making the healthiest and unhealthiest meals on the McDonalds nutrition calculator. Try out these investigations at home to see what happens if we don’t have enough calcium in our diet or eat too much sugar.

A trip to the dentist

Firstly, let’s look at what different drinks do to our teeth. If you can convince the tooth fairy to leave your teeth behind in the name of science, you can use real teeth. Otherwise, hard boiled eggs are a good substitute*. Pop each one in a plastic cup with a different drink; sugary cola, sugar-free cola, orange juice, fizzy water, tap water, anything you like. If you really want to see what acid does to your teeth, try putting one in vinegar! You might not think that you’d drink vinegar but bacteria in your mouth turn sugar to acid, so sugary things end up being acid in your mouth. This is why it is so important to brush your teeth! Leave the teeth or eggs in the drink for a week and then have a look for any changes.

Bendy bones

Want to see what happens to bones when they don’t have calcium in? Try bending a clean chicken bone to see how stiff it is, then pop it in vinegar for three days. Rinse it off and try bending it, has it gone all rubbery? Can you explain why?

*Note for super scientists: are eggs really a good substitute for teeth? Of course your teeth are much stronger than the eggshells but they are made of a similar material. The egg shells contain mainly calcium carbonate while tooth enamel is mainly calcium phosphate but both dissolve in acid.

You can find more cool experiments on our Home Science page…or book a Fab Scientist to visit your birthday party or school for lots of whizz-popping science fun!


Lava lamps work by taking two substances that don’t mix (usually wax and water) and then heating it to make the ‘lava’ move around. This version doesn’t need wax or heat, just cooking oil, coloured water and a bit of chemistry.

You will need:

•       1 empty plastic bottle (500ml is a good size, still water bottles work best as they have a flat bottom!).

•       Water

•       Food colouring

•       Oil (any vegetable oil will do)

•       Fizzy tablets (soluble vitamin C, cheap versions from a pound shop are perfect!)

•       Small light or torch (pound shop good for this too!)

•       A tray to catch any spillages

First we need to assemble the lava lamp. Stand the bottle on the tray and half fill with water, pop a few drops of food colouring in until you’re happy with the colour. Next, pour in the oil, nearly up to the top (you might need a funnel and a grown-up for this bit!). Leave it to settle for a few minutes, when all the oil is at the top it is ready.

Now to make it move. Drop in a small piece of a fizzy tablet and watch what happens. You should see the bubbles carrying the coloured water up through the oil. You can stand the bottle (carefully!) on a small light or hold a torch underneath it for a real lava lamp effect.

If you want to keep it for another day you can put the lid on … but you MUST wait for it to stop fizzing first. If you put the lid on too soon gas will build up and it could be dangerous.

So how does this work? Oil and water won’t mix because oil is hydrophobic (this means it does NOT like water). The fizzy tablet reacts with the water to make carbon dioxide gas (just like the vinegar and bicarbonate of soda experiments). These bubbles of gas are less dense, basically lighter, than the oil so can bubble up to the top.

You can find lots of experiments to try on our Home Science page…or invite a Fab Scientist to your birthday party or school for more cool science fun!
