Spengler: There's something very important I forgot to tell you.Anyway, if one placed 6 of them on custom tube equally spaced and can be turned on with one master switch and the tube is made out of whatever, and each one is focused to the length of 5 feet to a specific point, would they act as one?
Venkman: What?
Spengler: Don't cross the streams.
Venkman: Why?
Spengler: It would be bad.
Venkman: I'm fuzzy on the whole good/bad thing. What do you mean, "bad"?
Spengler: Try to imagine all life as you know it stopping instantaneously and every molecule in your body exploding at the speed of light.
Venkman: Right. That's bad! Okay. All right. Important safety tip! Thanks, Egon.
