How to Make Bouncy Balls

Science + Craft = Fun Learning Experience Learn How to make Bouncy Balls #diy

The kids and I are on a mission to make 1 fun science project every Friday all summer long. This last week we decided to try our hands at Homemade Bouncy Balls. I originally saw these on Pinterest and thought I would give them a shot.

PS. You can follow me on Pinterest, I am always pinning something fun :)

So we got out the supplies…

  • 1 Tbsp Borax
  • 1/2 Cup Warm Water
  • 2 Tbsp White School Glue
  • 1 Tbsp Cornstarch
  • Food Coloring

These amounts make 1 ball.

After mixed carefully scoop the glue mix into the borax mix while stirring.  Use a fork or other utensil to scoop up the glue mix after stirring. Start to form it into a ball with your hands. It will be moist. I had the best results by drying my hands well with a paper towel, and dabbing the outside of the ball.

Just keep rolling it around in your hands to shape it like a ball. This is when I handed it over the the kids and let them do the rolling.

The more you work with it the firmer it becomes.

The Verdict: These are a fun afternoon project. They do bounce and the kids had fun. These are the consistency of a very thick silly putty so they do loose their shape and need to be reformed. I also suggest keeping them in a ziploc so they don’t dry out completely and crumble.

    Borax really is a magical substance – so much science fun, depending on what it’s mixed with. I do wish I could find a definitive, unbiased analysis of its safety, though, as I know many moms are concerned about little ones coming in contact with it.
