While watching a small fire I had built, insperation struck me. What if I fill a paper cup with water, and then place it in the fire. I did this, and the cup didn't burn. Then I thought to myself, why don't they make watertight plastic tanks, whick are thin, and can be placed inside of walls, and roofs?

Pro(s):
1. The prevention of fire.
2. Keeping people and animals safe.

Con(s):
1. Cost, making all thin plastic tanks would be expensive.
2. One would have to cyle in freah water all the time into the tanks.

The Last Word:
Not than anyone would do this, but it seems like a good idea.
