My friend and I have a lot of ideas for liquid nitrogen experiments (and we will be safe! :)), but we have no idea where to order it from. If from an online source, try to be specific. If in reality, try to give a little input on the process. Thanks.

will somebody smarter that me please tell me how this works. okay, here goes. experiments done in the yesteryear told us that if a photon was split (?) the two parts would act as if they were still together. is this correct? this is the first part of my question. i'll get on to the...
