Want a higher proof alcohol? Go to the chemistry lab, borrow a condenser
and distill what ever alcohol you have one or more times. Remember to
watch closely the temperature of the alcohol in the heating flask. When
the temperature starts rising towards 100 degrees C, most of the alcohol
has been evaporated so the collecting flask must be removed.

While an alcohol-water mixture can be heated, that's distilling after
it *really* is dangerous since alcohol is very flammable and can be used
as a fuel.
