STEM DIY KIDS CRAFTS: Make your own bouncy ball kit through imagination. It can help improve children's hands-on ability and sense of color combination. The size can prevent loss from being swallowed by children. It also brings more fun for kids ages 8-12 with hexagonal and largest tennis or golf ball-sized bouncy balls. 

DIY COLORFUL BOUNCY BALLS: Kit materials can make 2 different shapes of bouncy balls. Bounce, roll, juggle, collect, and trade them. Watch the colorful particles magically turn cool and let kids embrace their creativity with the bouncy ball kit. 

NON-TOXIC AND SAFETY TEST: After the product safety test, it complies with relevant international toy safety regulations in Europe and the United States. We take the safety and well-being of children very seriously. Children can feel the joy of success in the process of DIY toys. The elastic crystal ball kit can replace bad habits such as watching TV and playing with mobile phones. 

FUN AND EDUCATIONAL GIFT FOR ALL AGES: Science projects don't usually come close to being both fun and engaging, but this kit delivers both! Great for solo play or as a group gathering gift.
