Your mini mad scientist loves mixing up soap bubbles in the sink so why not encourage that early love of experimenting with easy at-home science experiments? We’ve rounded up 20 classic concoctions, most of which call for on-hand ingredients. So get ready to make lightening, grow crystals and launch a rocket right in your homemade lab (well, you might want to do the rocket outside). Plus, we’ve rated each experiment from one to five sponges so you know the messiness factor ahead of time. Click through the gallery to get cooking!
Salt Crystal Feathers
A lesson in: Evaporation. And also awesomeness.
You’ve probably tried a salt crystal growing kit at some point in your life (5th grade Science Fair perhaps?) but Schooling a Monkey takes the idea to a new level with these Salt Crystal Feathers. This awe-inspiring project is deceptively simple and inexpensive to achieve, and requires just a wee bit of patience to see the results—kids will love checking in on the progress. Visit Schooling a Monkey now to get started.
