Halloween is a great time to try some spooky science tricks and experiments. Here at Science Sparks, we’ve been growing our collection of Halloween Science Experiments for years, and this year’s new Halloween science activities are the best yet!
These five Halloween science tricks are easy and stress-free to set up and almost always work perfectly!
Easy Halloween Science Tricks
Disappearing Spiders
Make spiders disappear using a trick of light! This very simple science activity uses just a glass and water. As water is poured into the glass, a drawing of a spider disappears.
Put a paper towel in water without it getting wet
This clever science trick allows you to put a paper towel in water without it getting wet. The secret is the paper towel needs to be in a glass.
Blow up a balloon without touching it
Inflate a pumpkin balloon using science. Baking soda and vinegar can be used to blow up a balloon while you sit back and watch.
Carbon dioxide is released in the reaction, which spreads through the container and into the balloon, causing it to inflate.
Halloween optical illusion
You can create a simple optical illusion using paper, pens and straws. Use my free template or draw your own.
Spooky sounds device
Use a plastic cup, ribbon and paper clip to make a spooky noise maker.
The cup acts like an amplifier. If you rub damp paper towel down the ribbon without the cup attached, no sound is made, but the cup amplifies the vibrations created by the movement, creating a creaky noise perfect for scaring trick or treaters!
