00:00He turned on the faucets and flooded his own restaurant, and he kept going until the rooms
00:06filled with water. You see, flood was already coming toward the building, and if he had left
00:11the rooms empty, dirty water would fill them. That would leave the rooms filled with mud,
00:16so he filled the restaurant with clean water first. Then the clean water inside pushed against
00:23the flood outside. This made the pressure almost the same on both sides, so the dirty water stayed
00:29out of the building. And when the flood finally passed, he pumped the clean water out. This kept
00:35the river mud out of the restaurant, and it helped save him thousands of dollars.
