That's Gross Science Lab
Chemistry has never been this gross--or fun! Features 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". 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! For ages 8 and up.
