The art of beer cooling

It's a burning hot day, and your beers have all gone warm

so... simply dig a hole in the sand

bury the beer a good 20cms down or so

cover it over nice and firmly

gather some fuel

and burn, closely monitoring

for a while

yep yep

then spread out the ash

and bring out the beer, cover over the ashes

and voila! The heat above draws it all out and the beer cools!!
