STEAM LAB – DIY Make Your Own Bouncy Ball

Last night we attended the first series of five in the STEAM LAB of one of the local libraries. This was the Science portion of it. The kids got to do 5 different hands on activities. The library did a very good job at organizing this event and I can’t wait for the next one which is Technology. I believe it has to do with programming robots.

The first station we stopped at was to make slime! Yes we did this on Saturday but this version was a whole lot quicker and easier. It only used two ingredients. I am not sure what the stuff was in the cup. The second ingredient was paint. They poured the choice of color into the cup and the kids had to mix it up. They had to smooth it around the sides of the cup. Then they had to pass it back and forth in their hands to get hardened. However, the long your stirred it in the cup the firmer it got. At first it was a little messy with the paint but it was washable. We stored them in one of those little sauce containers you get from a restaurant.


The next station was rocket straw launchers. The decorated and folded paper around the straw and taped it up. The kids put the paper at the end of the straw and then blew to launch from the other end of the straw. Lets just say those little buggers can fly! I think I darted a couple of them.

The Pom Pom Launcher was another favorite. The balloons were tied in a not and the top of the balloon is cut off. Then you take a plastic cup and cut the bottom off. You attach the balloon over the part you drink. (We ended up taping our balloon so it stayed on) Then you take a pom pom but it inside the cup. Hold it straight and pull the balloon down and let it go…it hits the pom pom up in the air. You can try to catch it with the cup. It was rather fun watching all the kids. I even got a few lucky catches myself. I think I got bombarded by a couple too. LOL

The Static Electricity Butterfly was kinda neat. The had the butterfly body all drawn out. The kids had to trace the wings on tissue paper. Once they were done tracing the glued the wings on to the butterfly. They only put glue on a small part near the end. Then they took a balloon rubbed it on their head and watched the tissue paper butterfly wings move. It was kinda neat. The little kids thought it was the coolest thing to see.

Now on to the last one!! I think this was my daughters favorite.

The last experiment was how to make a bouncy ball. The ingredients are pretty common for this one. It is fairly easy and it goes by quick. You just have to keep rolling it for a while and watch out where you set it because it can start to take the shape of whatever you set it on.

How to Make A Bouncy Ball


1/2 cup warm water

1 Tb Borax

1 Tb cornstarch

2 Tb white liquid glue

food coloring

In a cup mix the warm water and the borax.

In another cup mix the glue, cornstarch, and food coloring.

Pour the glue mixture into the water-borax cup…. We actually did the opposite….

The glue mixture will harden after 10 seconds. use a fork to take it out of the water. If the glue mixture is still sticky, squish it with your hands and dip it back into the water.

Roll the mixture in your hands to make a ball. The more you handle the mixture the firmer it will become.

Your done.

Notes: Keep in mind the balls will flatten a bit after sitting for a while. store them in a plastic contain or plastic bag. If they get flattened roll them between your palms again, this will bring them back to the ball shape.

Hope you enjoyed what we did in our STEAM LAB!!
