There are two different experiment kits available, unfortunately it's not possible to select a specific kit, so please allow us to select one on your behalf. Explosive Experiments: Create and launch a rocket, watch a volcano erupt, make a lava lamp and mix up some seriously slimy snot. Really Rotten Experiments: Includes a cockroach soap, fart pot and fake poo. You can also learn how the stomach works, with the aid of some green slime.
