Adam encounters one of the actual ghost trap props used on screen for Ghostbusters I and II, and this is a special one. Connected to the original transmitter controller used on set, this ghost trap is packed full of practical effects that not only let it open and close, but activate all the flashing and blinking lights that we saw in the films. Adam takes a look inside this iconic prop to see how the effects technicians made it work over 40 years ago!
