This was fun to try, and easy. Another upside is that it doesn’t take much time to accomplish. I think this a great idea to try for any type of party or holiday. It could even be a good hands-on activity for children to try.
Here's what you'll need:
- One ice cube tray (I got mine at the dollar store and it came in a two-pack for a $1)
- Regular Food Coloring (purchased both packs at Fred Meyer, two packs for $4)
- Neon Food coloring
Step 1: Pour the water into your ice cube tray, easy enough right?
Step 2: Add your food coloring into the water. One drop of each color was just fine.
This is what it should look like after you put the drops in:
Step 3: Put in the freezer. I left mine in the freezer for two hours and couldn’t wait any longer to use them. However, I found this could make a difference in how well each color lasts instead of just all the colors mixing and creating swamp water.
The finished experiment:
Overall, I really enjoyed this activity. I found that my orange a red were very similar, so I would add a couple more drops of red for next time to make the difference stand out a little more. Leave your ice cubes in the freezer for 4+ hours so you can enjoy the different layers of color longer. I would say though that this was a half fail, half success.
I wish you luck on your rainbow ice cubes and I hope you find a pot of gold at the end of it!
