Hello, I love all things science. I love to here about it and do things to see is I can do some of it. like sound, electronics, high volts and chemical experiments. um and other odd things. just now I am builiding a high voltage electro plater. using a coil from a microwave. a vacuum/presure pump from a fridge. the pumps from fridges are grate! 400PSI and -35psi. but I do know this is very very dangerous! just Dont ask what I have done before!!!
