It is every beer lover's summer nightmare - stuck in the middle of a park with the sun warming your drink. Thankfully, scientists have come up with a solution: the self-cooling beer can.
Slightly longer than a normal drink can, it simply needs a twist to cool its content down. It can, its inventors claim, cool a beer to the perfect temperature of 3C within three minutes.
The I C (Instant Cool) Can works by using water evaporation. The top half is surrounded by a layer of watery gel. The base contains a water-absorbing material in a vacuum, and a special heat-absorbing chamber.
When the bottom is twisted, a seal between the two halves is broken. The vacuum draws the gel, and the heat, into the base. The gel is absorbed by the material, the heat is absorbed by the chamber - and the drink gets cold.
Science the way it was meant to be used.
