Here at Science Sparks HQ, we love a bit of magic, whether it be a memory trick, slight of hand or even some science magic. These 10 easy science tricks for kids are great fun and mostly super simple. The density one is a little tricky and potentially messy, but well worth the effort for the incredible end result.
Easy Science Magic Tricks
Skewer through a balloon
First up is the skewer through a balloon trick. Take care with this one, as the skewer will be sharp, and it might be worth having a few spare balloons around until you get the hang of it.
Top Tip – place a little vegetable oil on the parts of the balloon that the skewer will poke through and push the skewer through the thickest parts of the balloon.
Leakproof Bag
Impress your friends with an easy leakproof bag. All you need for this one is a sealable sandwich bag and some super sharp pencils.
Top Tip – use very sharp pencils.
Make a coin disappear
Did you know you can make a coin disappear using just a glass and water?
Remove the shell from an egg without touching it!
Remove the shell from an egg without touching it, and then bounce the egg. If the egg bounces easily try it on different surfaces to compare the difference.
If, after all that, you STILL have an intact egg membrane, try making the shrinking the egg and then growing it again while learning about osmosis at the same time.
How to Defy Gravity
Did you know you can defy gravity using a magnet and a paper clip? This clever trick is sure to wow an audience!
Top tip – a strong magnet works best for this.
Always supervise children when using magnets
Egg in a Bottle Experiment
Watch an egg drop magically into a jar in this fun activity using air pressure ( not magic at all ).
How to make an unbreakable egg
With the shell on the egg this time, find out how to make an unbreakable egg.
Colour Changing Flowers
Bored of plain white petals? Place them in water and food colouring to change the colour!
Top tip – natural food colours don’t work for this.
Water that won’t mix
Do you know why the coloured water isn’t mixing with the non-coloured water in the image below? It’s a little density trick. Add lots of salt to the lower layer ( making it more dense ) so the less dense water on top doesn’t mix with the denser coloured lower layer.
Top tip: This also works with warm and cold water. Warm water is less dense than cold water.
Floating Eggs and Sinking Lemons
Try to make an egg float or a lemon sink? It might be trickier than you think.
Top tip – remove the skin to make a lemon sink!
Transforming Milk and Cream
Finally, how about turning milk into glue? Or cream into butter?
Cool a Drink in 3 Minutes
Chill a room temperature drink in 3 minutes using ice, salt and water! This is a great trick for a hot day. The same science is used to make ice cream in a bag.
Make an Unpoppable Balloon
Adult Supervision is needed for this trick
Find out how to put a balloon in a candle flame without it popping!
Do you have any more science tricks for us?

I think all of these experiential are so cool and captivating making me want to do some of them. I think the experiments you used are great since it’s fun and quite easy so mostly anyone can attempt making a replica of the project.

Activities like these can make learning so much fun for kids, it can even spark their enthusiasm towards science. Thanks for sharing these ideas!
