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!

Fishing for Ice

A lesson in: Freezing temperature.
Children living in snow-covered cities might witness their neighbors salting the driveway. Well, while that is definitely not for fun, this experiment is. Salt lowers the freezing point of ice so it melts, but it won’t be able to freeze unless it’s cold enough. See how activity blog The Science Kiddo made a clever game with this knowledge here.
