Make your own sure-pop bags and you’ll never have to buy a box of microwave popcorn again. That’s going to save you money, in addition to teaching you all about exploding vegetables. One pound of regular popping corn is enough to make 50 bags of microwave popcorn.
The puffy, powdery, sweeter-than-sweet candy pillows known as marshmallows are filled with scientific fun. When you make them at home, you’re experimenting with all kinds of cool natural principles: You’re showing how collagen behaves (that’s the protein that makes up all the connective tissue in your body); you’re discovering how sugar forms crystals (and what happens when it gets hot enough to melt); you’re demonstrating how foams are made; and you’re discovering how gelatin gels work. These marshmallows are going to make you so-o-o-o-o smart!
