Take a Measuring Cup on Backpacks

Sometimes a measuring cup is very handy, but if you are trying to reduce your packload, you don't want to pack gear you can do without.  A handy solution is to make your regular drinking cup into a measuring cup.  Get a 1/4 cup measuring cup, and pour 1/4 cup of water into your drinking cup.  Mark the liquid level, such as with a scratch with a knife.  Repeat until you have 1/4 cup markings totally 1 cup.  Then go pack and enlarge your scratches till they are substantial scratches.  I filled the scratches with "white out" then wiped away the excess. Bingo, your regular drinking cup is now a measuring cup.  Your pitiful scratchings probably won't be as pretty as mine, but give it a try.
