The hypothesis is that when Borax is dissolved in hot water and cooled, crystals will form.

To make a rainbow crystal, bend rainbow-colored pipe cleaners into a rainbow shape, dissolve Borax in hot water, and pour the solution into a bowl or container. Tie a string to a pencil and balance it on top of the bowl, then suspend the pipe cleaners in the solution. Wait 12-24 hours and observe as crystals grow on the pipe cleaners.

You will need Borax, warm water, string, pencil, colored pipe cleaners (red, orange, yellow, green, blue, purple), a large bowl, scissors, a cooking pot, and a tablespoon.

The crystals grew around the colored pipe cleaners and created beautiful, sparkly gems. The most interesting observation was that the crystals grew larger the longer they were left to sit in the solution.

This science project is unique because it allows you to create your own beautiful crystals in any shape you bend the pipe cleaners into while learning about how solutions can form crystals.

Bend the pipe cleaner into different shapes to make different crystals (see videos for making gemstones and snowflakes!) Try adding food coloring to the solution to see how it affects the color of the crystals. Instead of using pipe cleaners, try using different materials such as feathers or leaves to create a different type of crystal.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
