Young science lovers will enjoy this easy, hands-on experiment.




Making beautiful crystals at home is easy with just a few everyday household items. Try this fun science-based activity with your children — just wait for a bright day, since sunshine is a key element to growing crystals. 

What You Need

  • Black, dark blue, or dark purple construction paper
  • Small foil pie or brownie pan
