A huge, yucky science set with 45 different experiments to try! The National Geographic Super Gross Chemistry Set gives kids everything they need for 15 incredibly gross experiments, along with an extra experiment guide that contains an additional 30 experiments that can be conducted using common household items. With this science lab, kids will learn about the science behind polymers, non-Newtonian fluids, fluorescence, chemical reactions, and just how grossly awesome the human body can be! With this kit, kids can make a jar full of creepy eyeballs; burst blood cells; boil boogers and create snot bubbles; make atomic pee and farting slime; dissect a squishy brain; make a test tube vomit; create gooey, glowing worms and fungus; watch goo defy gravity; make a bubble goop swamp; and a whole lot more! This phenomenal STEM kit gives kids the chance to experience the scientific process in a hands-on way, just like a real scientist. There are so many activities and experiments to try, they'll be busy for hours! They’ll also learn about polymer science, chemical reactions, pH science, phosphorescence, and biology all while having a total blast! Our experiment guide contains kid-friendly, easy-to-follow instructions, and insight into the science at work in each
