Toysmith Light-Up Rail Twirler (Colors May Vary) (4-Pack)

$3.95 (as of January 4, 2019, 3:24 am)

The rail twirler is a reproduction of a classic retro toy, using magnets to allow a spinning wheel to perform gravity-defying stunts.
Magnets adhere the plastic wheel to the wire frame, allowing it to twirl along the track seemingly by magic.
The wheel lights up as it spins, for dazzling night-time effects.
