Copper sulfate crystals are among the easiest and most beautiful crystals that you can grow.

The brilliant blue crystals can be grown relatively quickly and can become quite large.

Here's how you can grow copper sulfate crystals yourself.

You can use duck tape to see an example of triboluminescence, the glow given off when some materials are subjected to mechanical stress or friction.

The duck tape triboluminescence project is extremely easy and only take a few seconds to try.

Natural geodes are hollow rock formations that contain deposits of crystals.Assuming you don't have a geological timeframe to obtain a geode, it's easy to make your own crystal geode using plaster of paris, alum, and food coloring. In this reaction vinegar is used to remove the protective coating from steel wool, allowing it to rust.Here's an easy science project you can do that proves propellants in common products are flammable and allows you to burn some bubbles.Blueprint paper is a specially-coated paper that turns blue where it is exposed to light, while areas kept in the dark remain white.Blueprints were one of the first ways to make copies of plans or drawings.
