Maybe this has already been addressed here but I have been trying to
come up with good uses for two liter plastic bottles for years. If any

Cut the bottom off, turn the bottom piece upside down and put it over the
vent opening on an outboard motor gasoline tank. It still allows air in but
is added protection against rain or dirt sneaking through the vent. (From a
local Florida boat dealer.)
