Rainbow Crystals Science Experiment
In this fun and easy crystal science experiment, we’re going to make rainbow crystals.
Note: Since hot water in involved, please insure adult supervision is utilized.
- Jars or vases
- Borax powder (This can be found online or in the laundry aisle of the grocery store)
- Pipe cleaners in multiple rainbow colors
- Popsicle sticks
- Boil three cups of water.
- Measure 9 tablespoons of Borax powder into a bowl.
- Slowly pour the boiling water into the bowl with the Borax powder.
- Stir with a Popsicle stick. The water will look cloudy.
- Now fill your jars with the Borax solution.
- Next, cut the pipe cleaners to fit into your jar.
- Take a Popsicle stick and fold the top of the pipe cleaners along the stick. The idea is to lay the Popsicle stick along the jar so the pipe cleaners can dangle down into the Borax solution.
- Now place your pipe cleaners into the jar and wait overnight. When you awake, you should see that rainbow crystals have grown on your multi-colored pipe cleaners!
How it Works:
The Borax dissolves in the heated water and creates a saturated solution. As the water cools, it becomes less able to hold the Borax. The Borax then clings to the pipe cleaners and starts forming crystals.
Make This A Science Project:
Experiment with different items on which the Borax crystals could form. Add salt to the solution.
