The new Mathmos Blimp has a press-touch mechanism integrated into its base, so no more fumbling around looking for switches. When on it runs through the full colour spectrum emitting a glow that is redolent of sweet shop colours - warm, rich and bright - and when not in use their milky-white shapes are decoratively cool.

Simply plug in the power supply to your wall socket and press on the top of the glass shade to switch it on. Then just enjoy the psychedelic and ambient atmospheric feel that it creates. Ideal for producing a cool effect at any house party....
