You wait six months for one Mathmos product, and then three come along at once. Like Thaw and Float, Melt continues the candlelight theme that was devised as a design competition open to all. Basically, a "send in your design and if it's good we'll make it" deal. Unfortunately, Melt is the least imaginative of the project so far. It has the appearance of melted wax without all the fun: making little canyons for the wax to run down, or covering your fingertips and imagining committing untraceable crimes. Their fried egg demo doesn't help things either...

Available in three colours, in packs of two, for £10/$25 from Mathmos.
