Liquid Nitrogen Bomb
If you have worked with liquid nitrogen you know that it is cold and that if it touches you it will roll off your hand like water or turn into gas. But there are ways you can make it really dangerous. liquid nitrogen is more dence than nitrogen as a gas which is not surprising. Nitrogine as it self without oxygen is really bad for you it can sufficate you and you wont even know it is doing it. A little fact is that nitrogen suffication has been cleared as a humanian way to execute people. If you make a liquid nitrogen bomb as it is called always do it outside and for a purpose not to harm anyone. If you put liquid nitrogen in a contaner and seel the top and if the container is the right density it will explode possibly harming people but if the container is not dense enough it will blow a hole right through and will steadily leak air. Liquid nitrogen takes up 600 times less space than the gass version of nitrogen so thats why it expands when the pressue is let off and explodes the container its in. Someone who works in lab did a test nitrogen bomb and their water bottle went thirty feet in the air one of the observers was ex-military and said the blast was about the same as a 3/4 stick of dynamite. Most people that make these do it in a pool or in a spot away from people to keep people safe I HIGHLY advise doing it away from people.

what Alcoholism dose to the body
Alcolism is a growing diseas in America and is a physical diseas which i thought didnt make much sense. The American Health Organisation says it is a diseas that efects the whole Family which againg didnt make sense. But i found out at an Alanon meeting that it infects the Alcholics liver and makes them crave it and that when the Alchoholic is drunk is how it effects the family. An Alchoholics liver is missing parts that it needs and terefore it craves Alcohol.
Plasma energy
Plasma is a liquid that when given electricity can shine bright, the lights in schools and office buildings are plasma lights.

Plasma can also be used for entertainment perpouses with plasma balls. Plasma balls work because the gas has a metal electrode filled with gas kept under an intermediate pressure. First an electric voltage is aplied to the electrode which acts as a conductor used to make contact with a nonmetalic part of a circut.
Plasma has been used also in ways of creating a way to fix roads. Scientists made a machine to turn trash into the black stuff on the highway to fix it. Also students at UCLA are using plasma for themonuclear fusion which "fuses" two light nuclei to form a new heavier Nuclious. Thier 192 laser beams will work with an energy of 1.8 Megajoules and 500 Terawat more than 500 times the U.S. peak generating power on to a millimeter sized DT fuel Capsel in the center of thier 10 meter diameter test chamber.
