Here at Science Sparks HQ we love a bit of magic, whether it be a memory trick, slight of hand or even science magic. These 10 easy science tricks for kids are great fun and mostly super simple. The density one is a little tricky and possibly 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, the skewer will be sharp and it might be worth having a few spare balloons around until you get the hang of it.
Leakproof Bag Experiment
Impress your friends with an easy leakproof bag. All you need for this one is a sealable sandwich bag and some super sharp pencils.

How to 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!
Try removing the shell from an egg without touching it and then bounce it. 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 egg shrink and then grow 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!

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 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!

Water that won’t mix
Do you know why the coloured water isn’t mixing with the non coloured water? 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.
Floating Eggs and Sinking Lemons
Try to make an egg float or a lemon sink? It might be trickier than you think.

Transforming Milk and Cream
Finally, how about turning milk into glue? Or cream into butter?
Do you have any more science tricks for us?

I am intrigued by those egg ones! How cool.
Brilliant. I am signing. Up to your blog! 🙂
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!
