That's Gross Science Lab

Chemistry has never been this gross--or fun Featuring a motorized toilet bowl mixer with real flushing sounds and a gross-tastic lab book packed with 26 super gross experiments--including "Foaming Flush," "Snot Slime," "Potty Putty," and "Stink Bubbles"--the gross-out fun will last for hours

But there's more to this chemistry kit than just cheap, gross-out, laughs. As you craft these disgusting experiments, you'll learn about the chemical reactions that make the awesome gross-ness happen. Plus, you'll get the scoop on polymers, diffusion, and gas expansion, and how those factor into the fun
