Valentine’s Day Crystal Heart

My oldest is super into science experiments lately. He received a bunch of science related gifts for Christmas, maybe he’ll grow up to be a scientist. But for now Mom will find fun experiments for him to conduct. With Valentine’s day approaching I thought we’d do a themed project. Over the weekend the boys and I made crystallized hearts. It was a super simple project and the boys had a blast running back and forth all day checking for changes. So here are the instructions if you want to conduct this science experiment too.

What You’ll Need:

  • Borax
  • One glass jar per crystallized item
  • Measuring cup (1 cup) and measuring spoon (1 tablespoon)
  • Pipe cleaners 
  • Popsicle stick or pencil, really anything to wrap the pipe cleaner around
  • Twine or any kind of string to tie around the pencil/popsicle stick
  • Pot to boil water in

Let’s Get Started:

  1. So we started out by boiling the water. You’ll need 4 tablespoons of borax per one cup of water. Boil and borax until the borax is dissolved. 
  2. While the water/borax mixture was heating up I shaped the pipe cleaners into hearts. Now we did hearts because this was our Valentine’s day experiment, however, you could make ANY shape you want. 
  3. Once the borax is dissolved, you pour it into your jars. We had two jars so I poured about a cup into each jar. Side note, plastic jars will work but we found (after our first attempt at this experiment) that glass jars work better. 
  4. Once your jars are filled, wrap the end of the pipe cleaner around your Popsicle stick or whatever you are using to hold your crystallized item. Place in the water and wait for the magic to happen.

After a little over 24 hours here was our result. 

I feel like we left ours in a little long because the crystals started to climb up the twine. The boys didn’t mind. They really loved this experiment. They kept asking to check on them. Little ones get curious but be sure to not move or shake the glasses. Lorenzo was so excited to share this with his friends at school. He even wanted me to email this experiment to his teacher! If you and your little scientists conduct this experiments be sure to leave a comment below. I’d love to see pictures of all the different shapes you use!
