Mixing Colors with Water Balloons
Here’s what you’ll need:  liquid watercolors (you can use food coloring, but it might stain clothes/hands), water balloon pumper, primary colored water balloons, water, and a dish tub or plastic container.
This is the type of liquid watercolors that we use.
  Â
 1. Inflate the water balloons using each individual color inside the coordinating color of water balloon. We have this water balloon pumping station and love it because of the tie-not feature (it totally saves our hands from having to tie a million water balloons). :)
 Â
 2. Find a place (outside) to begin the color-mixing fun!
 Â
 3. Have your child choose two colors of balloons…
 Â
 …and pop them in whatever way he/she would like. Stomp, squeeze, or throw!
 Â
 4. Swish the water around to see what color the two balloons create.
 Â
 Little Brother thought that this activity was pretty cool. :)
 Â
5. Dump out the contents each time into a larger container…
 Â
 …and see what happens when all the colors are mixed together!
