I bought this as a Christmas gift for my grandson. Looks like it will provide lots of indoor entertainment during this pandemic and colder weather.
Awesome for playing with my nieces, but the walls dry put and become unusable after about 2 days. The ones they made when I was younger had way more bounce and never dried out like these.
Fun for the whole family
Awesome products! My sons and his cousins had lots of fun making their own bouncy balls. The package comes with many plastic powders so we weren't even worried about running out of raw materials after having made 9 balls. They loved the grow balls the most!
This kit was cool. Not too time Consuming. Served as fun for 3hrs for multiple children, just to build. Makes many bouncy balls of countless variety. It can be used on more than one occasion. Kit cleanup tip: water activates the crystals. Anywhere there may be water the crystals will turn to rubber. I highly recommend cleaning parts in a separate vessel or outside. Do not put down drain.
