Have you ever fired up the grill, put all kinds of great stuff on it & run out propane? That's maddening. Some gas grills have gauges. If yours doesn't, here's an easy way to tell how much gas you have left...

Pour a glass of hot water down the side of the tank. Feel it with your hand, moving down the side. It will be hot at the top. As you move down, it gets colder when you hit the level of the propane.
