1. I've understood that Americans sometimes have big hands made of foam with pointing index finger in sporting events. Is something done with these hands, or do they just keep them with them? Do they symbolize something?
2. I've heard that dish washing machine uses less water than washing dishes by hand, and frankly, I don't believe it. If it is true, does the more poisonous dish washing substance (what is it called, the thing that's mixed with water) compensate the lesser use of water from environmental point of view?
