Get stranded in Antarctica.
A desert is a region with very little precipitation (usually less
than 25 cm annually). Antarctica gets virtually no rain or snow.
Plus, despite being surrounded by ocean, it is made up of fresh water.
So, drink up! (You have an icepick, don't you?)
Here is an easy way to pick up a little pocket money: bet someone that
they don't know which is the largest desert in the world. The answer,
of course, is Antarctica, being about 50% larger than the Sahara desert.
