Everyone will want try it , it's so impressive and easy - but for the really skillful there's an extra skill level. Hold the wire guides vertical , with magnets on disc inside the rails. Basically you spin a (magnetised, flashing) disc on wire guide rails - but there's a knack to it. (Start off slow, speed up once the disc is spinning and flashing). The faster you go the more dramatic the colour display. Adults will demand a turn too! (Great entertainment at parties). The extra level? Well, you can get the disc to jump off - and back on - the guides (place magnets on disc on OUTside of rails, get spinning, turn the rails horizontal, then flick the disc off - not too far, use magnets to retrieve disc ).
