OverviewAmazing Spheres are truly amazing! You get colourful and clear spheres with this kit. Place the clear tiny beads in water and watch as the expand into huge slippery bouncy clear marble balls. They look invisible in water so this can be a great trick and science experiment! Use the included coloured spheres and watch as the tiny colourful beads grow into colourful marble sized spheres. Use the included giant test tube and just add water! Observe as the once tiny beads grow into an incredible amount of colourful round and slippery "marbles". But that's not all! Roll 'em, mix 'em, squish 'em, throw 'em even bounce 'em! An incredibly cool science transformation and science lesson on absorption of water and super absorbent polymers.
