Have you ever mixed together salt and pepper? Isn't it fun to see how all of those tiny grains of salt and pepper mix together! But what if you had to separate them out again? Do you have nightmares of tiny tweezers, a magnifying glass, and hours spent picking grains of salt and pepper apart? Don't be afraid, there is another way! Using the differences in solubility between salt and pepper, you can find out the simple "solution" to this problem.

Making your own bubble solution is fun, but sometimes the bubbles don't seem to work as well as the solutions you buy in the store. In this experiment you can test if adding corn syrup or glycerin to your bubble solution will make it just as good as the stuff you can buy. This experiment will have you blowing bubbles!

Have you ever wondered how fun toys like Silly Putty, Gak, and Slime are made? These products are so much fun because of the properties of polymers, which make them delightfully bouncy, stretchy, sticky, moldable, breakable, hard, soft, and just plain fun! In this experiment you can be the developer of your own putty product by changing the ratio of ingredients to change the physical properties of your putty polymer. By describing the physical properties of your results, you can choose the best recipe for your new product.

Did you know that your body has a built-in cooler? And it might not be what you think! Sweat is produced when you are hot, but its purpose is actually to cool your body as the water in it evaporates from your skin. In this science fair project, you'll use the energy produced when water evaporates to cool down chocolate-covered candy so it doesn't melt.

Do you ever wonder how markers are made? Where do all of those colors come from? Many of the colorful dyes we use come from plant pigments. Pigments are what make the world around us so colorful. How do chemists turn those natural plant pigments into art supplies? In this science project, become a chemist and make your own marker out of a drinking straw and homemade plant dye!

Crystals come in all different shapes and sizes. However, the purest and cleanest crystals are usually also the ones that grow to be the largest in size. In this science fair project, you will compare the size and shape of crystals grown in three different temperature conditions: room temperature, in the refrigerator, and in an ice bath. With just water and borax, a household cleaning product, you can discover the best recrystallization method for growing large, pure crystals.
