Now you can paint the sky with light and color. Spinballs are LED poi balls that are soft and light weight enough for children to use! Poi is a performance art that requires artists to swing lit balls rhythmically and geometrically to create visual effects. We love Spin balls because it so easy to get started, just grab on the leashes of the two LED balls and start swinging! You must have patience and practice hard though if you want to master cool tricks to perform! They are so light weight and easy to carry, that you can bring them with you where ever you go. It is so fun to perform on the beach! Spinballs improves balance, coordination, reflexes and motor skills, as well as boosting confidence and creating a sense of accomplishment. By learning the moves and motions, using Spinballs helps improve mental awareness and rhythm, concentration, processing speeds, and memory. Suggested for ages 6 and up.
