Fast Acting Insta-Snow For Science & Chemistry Fun: Look at it grow, kids—adding water to the polymer snow mix makes it grow up to 100 times in size. A soft pile of fresh snow within seconds, young scientists are excited to see the whole process and fluffy results. No mixing necessary, and the snow can be dried out to reuse for future STEM lessons again and again. Perfect gifts for curious science lovers of all ages, and a must-have chemistry kit for homeschoolers, classrooms, and sensory tables. Include it in party gift bags or as a winter-themed stocking stuffer. Easy and enthralling every time.
