When you think backyard, you think playing, relaxing and grilling, right? But this summer, think “testing hypotheses” too. We couldn’t think of a better area than your spacious, self-cleaning (thanks, rain!) yard to set up experiments all summer long. Flip through to find one to try!

Baking soda and vinegar volcanoes are so last decade. This generation is all about dropping Mentos into 2-liters to make their mark on the science world. Steve Spangler has the need-to-know details on this engaging experiment. Plus they’ve got a few add-ons that move beyond explaining why the explosion happens, to figuring out cool adaptations you can try at home.
