Picked one of these up for my little boy's birthday this morning at Tesco in Swansea. Not sure if it is nationwide and still showing £78 online.
Defy gravity and dazzle your friends with the award-winning MagNext iCoaster. This incredibly creative 64-piece kit combines magnetic stunt tracks with a perpetual magnetic elevator, resulting in a rollercoaster where the fun never stops.
Easy and quick to assemble, the eighteen sleek tracks snap together with light-up sensors, adjustable towers and seven hyper stunts to give the five magnetic marbles the ride of their life.
Check out the ten suggested track configurations, or experiment with your own risky, physics-powered designs. To complete the experience, turn on one of 20 background music tracks or plug in your own MP3 player.
