It's Halloween! While I am well past the age of trick-or-treating, this is still one holiday I love getting into. So upon finding this video a while ago, I thought "Hey, I wonder what other experiments I can put a Halloween spin on..?"

So here is a list compiled from our Free Experiments section of activities you may like to consider adding to your line up of festivities!
silver metal nail fake red blood fake wound skin
Fake Blood!

Our favourite recipe is chocolate topping with red food colouring (with a tiny drop of blue). But if you want to make it more educational, check out this fun and tasty hands-on activity about the different components of blood!

clear plastic cup blue slime dripping off hand black background

Classic, and adds dribbly grossness to everything!

brown sultanas
Dancing Worms!

Replace the raisins in this experiment with gummy worms and watch them wriggle around as if they're alive!

btn more

psyllium flubber green and brown
Glowing flubber!

Add a crushed up Vitamin B tablet to the water before you heat the mixture, and it will glow under a blacklight!

Volcano eruption experiment (person poring detergent into a cup in front of a mound of sand)
Pumpkin Volcano!

Another well-loved experiment, why not pop it in a hollowed out pumpkin or your expertly-carved jack-o-lantern and watch it explode and froth!

Black light UV blue background dark blue HI!
Spooky notes!

Messages left by spirits? Or just some fun science!

blue fizzics balloon with silver coke can yellow background
Static ghoulies!

Switch the can for scary tissue paper cutouts and watch them move and float all on their own!

egg with bubbles in a clear plastic cup of white vinegar
Alien eggs!

This article suggests a great way to turn this experiment into a creepy display with some extra food colouring and corn syrup!

teabag with white tag on white table
Flying ghosts!

Decorate the teabag before lighting it with a match! I recommend a spooky ghost face!
