Ready to try this science project with how to grow crystals at home.

Crystal experiments

For this crystal growing science project all you need are a few simple materials:

  • Coal (like you use on a bbq grill (I’ve heard cut up sponges will work too)
  • Water in a squirt bottle
  • 3 tablespoons uniodized salt
  • 3 tablespoons ammonia (smells really strong so please use in a well ventilated area with the help of an adult)
  • 6 tablespoons bluing
  • morton salt (regular table salt)
  • liquid food coloring (simple stuff you find in the cake aisle is what we used)
  • glass pie pan to hold your crystals

Grow your own crystals

Day 3 – You have some very pretty and delicate crystals forming. You can be done at this point if you are satisfied or you can crank it u a notch and watch the crystals start to grow like CRAZY! Pour an additional mixture of 2 Tablespoons ammonia, 2 Tablespoons water, and 2 Tablespoons bluing in the bottom of the pan, careful not to disturb the delicate crystals. This will get pulled up through the coal as a food source.

How to grow crystals with salt

By day 12 our coal had all but dissapeared into large growths of crystal. We should have added more food coloring the 2nd time to get more colored formations. Instead the colored crystals started to get burried by large white, cauliflower looking crystals.

Have your children use a magnifying glass to observe the crystal up close. Pull off a piece and analyze what it feels like. Is it still delicate?

Now make sure to wash your hands with soap and water, throw out your project, and wash the pan and surface carefully.
