Poliound, As for dangerous, I think everytime we pick up a cell phone we are risking explosion just as well. Same goes for many, many daily used items ran by lithium batteries, Even playstation 3 has lithium batteries in their controllers that kids use. Also I do agree on teachers telling children that they are bad just to keep them away, But that can kick you back in the .... when your child would say, daddy thats bad for you, but after a little explanation they need to know its to help stop smoking altogether.
