Marshmallows are a delicious, fluffy staple of summer, campouts, and barbecues. Did you know that there isn’t really much to them? It’s true. The best way to see what really comprises a marshmallow is to put it to the Marshmallow Masher pressure test. You’ll use the power of air to demonstrate what you’re really eating when you roasting ‘mallows this summer. Want more experiments like this?
Graph P versus V and accurately determine atmospheric pressure using a syringe, pressurized soda bottle. Continue reading
Marshmallows are a tasty, fluffy staple of summertime s’mores, campouts, and backyard barbecues. There really isn’t very much to them, either. The scientific way to see what really fills a marshmallow is to put it to the Marshmallow Masher test. You use a property of air to demonstrate what’s really on the inside of those roasted ‘mallows you make around a campfire. It’s not all sugar.
