TV Show EXTRA CREDIT

 Two days ago I was watching Myth-busters, and I noticed something interesting that I saw. When they shot the hot water heater they said their estimates of the hight and speed of the rocket. The rocket went about 500-ft. and when it came down the whole bottom was shot off like the cork shooting out of a test tube lab, except the cork stays behind (the bottom of the water heater is the cork the rest is the test tube). Also the chemical reaction was just the expanding of pressure instead of the CO2 pressure created by mixing baking soda and vinegar. They tested the this in California. I think this is good because this could be a real danger if you plug up all the pressure release valves on your water heater or they fail. also it proved that the heater could go through two-stories plus a roof so if this hit you bye bye. You get a free ride about 500-ft up but you probably will not make it. In conclusion many people can use this advice to help make safer water heaters that just burst lightly outward so that only the water is released and not shooting the heater upward.
