Homeschool STEM: Water Balloon Physics

water balloon

Kids love water balloons, so what’s more fun than teaching a bit of physics using water balloons?! And, to make this experiment extra fun (and extra messy), we’re going to add paint to the mix! Check it out:

What you need:

  • Balloons
  • Several different colors of paint (make sure it can be washed off anything with water)
  • Water

What to do:

  • The idea here is to demonstrate how balloons falling from a greater height will fall faster and create a bigger splatter pattern when they hit the ground than balloons falling from a lower height. So, what you’ll want to do first is find or set up some sort of flat surface where it will be easiest to see the splatter. Doing this outside is probably your best bet.
  • Fill each balloon with a mixture of paint and water. You don’t want too much water in there, so make sure the liquid maintains a consistency on the thicker side. Use as many balloons as you like for a larger or smaller number of examples.
  • Drop each balloon from a different height. After each drop, have your kids observe the splatter patterns and notice differences between them.
  • For older kids, you might want to have them measure the height from which each balloon was dropped and the radius of the splatter pattern and create a graph with their results.
