It’s time to turn your home into a laboratory. Learn about static energy and re-create homemade lightning. See a rocket ship launch with the science of chemical reactions. Here are 17 experiments to get those brain gears churning — click through to see them all. We’ve even ranked the messiness factor from one to five sponges so you know what to expect.
A Lesson In: Polymers. Is it a liquid or solid? The answer is both! This DIY slime — made from glue, borax and water — is also known as a polymer (molecules that can stick close together to be a solid or spread apart and take liquid form). And it’s all thanks to borax, which acts as a binder to prevent the glue from going completely liquid. Prolong the life of your goo by keeping it in an airtight container in the fridge.
