Yes, but for the young and impressionable reading this, keep it mind it will cause serious freeze burns as it comes out of the tank if it is not regulated and will cause loss of consciousness. If said tank is still flowing when you lose consciousness you may die from breathing too much. I have had the joy of playing with big nitrous tanks before and seen what could have been really ugly fatal accidents. Also the nitrous used in cars as a fuel is not safe for breathing as far as I know.
