Fun Experiments Full of Blood, Bugs, Poop and More

From squirming insects to smelly human bodies, there’s so much to explore with these excitingly icky experiments. Learn about everything from food, bugs, germs and poop to all the weird and wonderful things you’re made of. Taste and tear through a variety of edible models of skin, blood and scabs. Rip open fake stomachs, create blood baths and test your own body to see just how gross human beings can get.

Don’t stop there, though! Get your friends and family involved, and give them bath bombs full of bugs or see how long it takes them to detect different smells from across the room. There are so many ways to disgust and amuse those around you, from smelly cow burps and slimy frogspawn to homemade poo launchers and experiments that explode with fizzy juices. No matter which experiment you choose, you’ll have fun being gross.
