Stumpy the Odious Ogre; welcomes you to Gross Science, the totally awesome kit that will take you on a voyage of discovery of just how disgusting the human body can be.

You can perform 12 horrid, yucky activities that will teach you about things such as how farts brew, what a poo is made from and how one is formed, why scabs and boils form and make your own, how you can make a life-size bouncy eyeball and wobbly brain, how you can make edible skin.

Whilst at the same time having loads and gooey, sticky, gross-out fun.

Are you ready? Be warned, it could get pretty GROSS!
