The POOF-Slinky 0SA509 Scientific Explorer My First Fizzy Foamy Science Kit will have children young and old mixing safe powders to create solutions that foam and fizz. In this educational, make-it-yourself kit you’ll make bubbles and even make a volcano erupt! Along the way, you’ll learn some cool science about fizz and foam and how to make it bigger and better. Questions like “What happens when acids and bases clash?” will be answered, while these experiments will encourage the development of science and math skills. In each of the (7) activities, your child will get to act and think like a real scientist. They’ll ask questions and make observations using four of their five senses. They won’t taste anything, but they’ll use their eyes to see, nose to smell, ears to hear and hands and fingers to feel. Questions asked in this kit will be answered as your young scientist measures, predicts and investigates using safe chemicals and common household materials. Time to get fizzy and foamy!
