    Science Tricks for Kids

    April 25, 2019 By Emma Vanstone 4 Comments

    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?

    Disappearing Coin Trick - fun science magic trick

    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.

    Two pint glasses balanced on top of each other. One is full of clear water and one water coloured blue with salt. the two do not mix as the salt makes the water in the bottom glass more dense than that in the top.

    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 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.
