This is a little project that I dreamed up but wasn’t really sure if it would work. After our experiment with turning juice into a solid, my mind started reeling with other possibilities! So, this is the result, Homemade Paintball Bombs! They worked and they are pretty darn awesome!
These homemade paintball bombs are solid on the outside and liquid on the inside. When you throw them they splat and explode all over. My kids literally went NUTS over these. I can see this being a pretty cool party activity, or a fun outdoor summer game.
How to Make Homemade Paintball Bombs
Start by getting out a cup for each color of paint you want to use. We used disposable cups for less mess.
In each cup mix:
1 Tablespoon of Tempera paint
3/4 c. of water
1 Teaspoon of Sodium Alginate
Mix well and let it sit for about 2 hours.
After a few hours, mix 2 Tablespoons of Calcium Chloride with a few cups of cold water in a large glass pan.
Drop tablespoons of the mixture into the water and calcium mixture. They will quickly harden on the outside. Remove them to a plate or tray. If you want them to be more uniform, you can use a silicone mold to make the balls of paint.
Now here comes the FUN part!
Take your kids outside to play with these homemade paintball bombs! Make sure they are wearing something you don’t care much about. Even with washable paint, it was tough to get out of their clothes.
Watch my kids in action!
For a party it would be a blast to have everyone wearing a white t-shirt so you can see who got hit. Or have teams and each team has their own color. You can set up a target, made of poster board, or draw one on the ground with sidewalk chalk.
