We never know how much gas is in the tank on our grill. Once we, you know I don't mean me, (I've never brought a tank to be filled.) brought the tank to get filled & it didn't need gas. Twice while cooking we ran out prior to finishing our cooking. When I heard of this tip I was so excited. It changed my life!
Slowly pour one cup of boiling water along the side of the tank. Wait a few seconds.
Feel along the side of the tank when you feel the temperature go from warm to cold that is the mark as to how much gas is in the tank.
Never again will I have to worry about running out of gas in the middle of preparing a meal! By the way, Mick was never concerned I was going to blow up the house. Although, he did leave for work while I was testing the tip. : )
