Want to make sure you have enough propane is left in your tank before you fire up the grill? Try this tip from my favorite magazine Louisiana Kitchen & Culture:

If your propane tank for your gas grill does not have a gauge or indicator and you're not sure you have enough propane left to get dinner on the table, pour some very hot water down the side of the tank. The water will heat up the empty portion of the tank; the portion of the tank holding propane will remain cool.
