It’s Crystal Clear, Kids Will Love This Project Science has never been this much fun before! Get ready for an easy science experiment that will blow your mind! All you’ll need to do is add our special powder to hot water, mix it well, and then add your crystal seed. It’s as easy as 1-2-3. Our step by step instructions will make it easy for kids to follow along and they'll even learn how natural crystals grow and are formed. With a Little Help, They’ll Go a Long Way Kids will need a little help boiling the water for this experiment. Otherwise, they can mostly do it on their own. Build their confidence by letting them discover their scientific abilities and independence. Kids will learn precision and patience because the crystal needs 7 days to fully grow! They’ll wake up every morning eager to check the progress of their crystal.
