Problem: beer cans that get too hot. Answer:
… 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.
You see? Now why didn’t anyone think of that before? Because they were too busy thinking about big insoluble problems instead of small(er – hot beer is no small problem) soluble ones is why.
I spent last night pondering, among other things, Europe’s demographic decline. What the hell can I do to stop that? Have some kids? Maybe, but not nearly enough kids to solve the problem. And I never really have been one for actually solving problems, even small ones. What I can do is salute those who do solve problems. On the whole, they are called “capitalists”.
My thanks to Dave Barry. Quite what the impact of self-cooling beer cans will be on Europe’s demographic decline is beyond the scope of this posting.
