Uses For A Disposable Pie Tin

After listing uses for duct tape, clothes pins and a safety pin I found myself wondering what to do next. And then it hit me - why not the under-utilized pie tin? Here are some ideas I came up with; please share yours by commenting below.

Pet water/food dish
Emergency singling device (flashing it in the sun like a mirror)
Emergency pan for cooking
Bowl /plate to eat from
Put one in the bottom of a Dutch oven to save cleaning time
Cheap way to do self-serve food when camping, on a picnic, at a party, etc
Cover food up to keep it warm and keep bugs out
Garbage bowl: fill with the rubbish you produce while cooking
Use in the bottom of a solar still to collect the water
Use a pan for gold panning in a stream
Shovel for a young child on the beach
Turn it into a boat to float on a pond
Frisbee
Use as target in rock toss game
Part of a costume
Put in tent /rv to hold small things like coins, watch, keys, etc
Turn into a mask
Decorate several and hang from a string to make a mobile
Center piece - fill with rocks/sand and place a candle in the middle
Put behind a candle to reflect more of the light forward
Poke holes in it to use as a dry goods sifter or as a colander in a pinch
Make a potpourri pie; put potpourri in the tin, cover with strips of tan felt, staple/glue the felt to the tin, sprinkle cinnamon on the felt.
Child’s instrument: fill with rice, beans, small bells, etc. Attach another tin to the top and shake.
Hang several from tree branches to keep away scavengers
If all else fails use it to make a pie

What other uses can you think of?
