Tobar Make Your Own Bouncy Balls Craft Kit

Product Information

It was a bit sticky to start with, but after 5 minutes of drying it is a pretty good bouncy ball and my son proudly showed it to his friends later in the day.

When you briefly add water, the PVA is soluble, meaning the long polymers are able to move around in the water, and get tangled up with molecules from adjacent granules. Surprise Your Kids With A Fantastic Gift: spoil your children with a unique, super fun, and educational gift set that is great for birthday party activities for kids or sleepover games and the ideal way to spend some quality time as a family!

I've seen them marketed as an educational science activity, and it's quite possible that if you pay a bit more, you get something that tells you a bit about what you're doing and why, but there was nothing like this in the cheap kit. A mixture of up to five colours can be poured into one of the three supplied moulds (one large, spherical design and two small, irregularly shaped ones), immersed in water, and then split open after four minutes to reveal a superbly bouncy creation.

When putting the granules into the mould, we shook it a few times to make them pack a little more closely. Galt have come up with a kit that allows children to create their very own bouncy balls from scratch. A great gift idea for space fanatics, this NASA Make Your Own Planet Bouncy Balls set is sure to be a hit. The polyvinyl alcohol (PVA) is a polymer made of lots of repeating units of carbon, hydrogen and oxygen. This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.Refill kits are sold separately, and contain enough polymer crystals to make 12 more super bouncing balls. Students use initial and final bounce heights to determine the energy lost to the environment during a bounce. Its one that is very hands on and great for children who may sensory seek or like to work with their hands.
