Big Bag of Science

This is big. We mean really BIG! The Big Bag of Science is meant to amaze you and your friends with over 70 activities. Make a blizzard of snow, erupt a 30' geyser, find the iron in your breakfast cereal, learn why you hate vegetables, make water disappear, and so much more. Safety tested, with experiments for learning about chemistry, physics, climate, biology, and magnets, this set is amazing! (Your next science fair project will be outstanding.)
