Science for Kids: Overnight Crystal Garden - Babble Dabble Do (uses epsom salts)
Watch your veggies grow! (A great way to teach kids how vegetables grow).
Homemade Bath Salts. SO EASY! I made these for a shower gifts. Just use Epsom Salt, it's cheap! I use scented oil, and coloring found at the craft store, in the soap making isle. no real measuring. just pour Epsom salt in a bowl, add scented oil and a few drops of coloring, mix well. DONE! can also be mixed in a zip lock bag. I filled Narrow Candy bags, designed my own label and "laminated" it with wide clear shipping tape wider than label and stuck on bag. Added a bow. So many possibilities!
