Super 8: loading a cart onto a Lomo developing tank spiral

A short video I made for a friend on how I load Super 8 carts onto the Lomo UPB-1A spiral.
Many people break open the cartridge in complete darkness. I don't use this method, instead I load the spiral by directly pulling the film out of the cartridge.
I cut a small strip of aluminium wire and jam into a tiny recess in the cart to force down the pressure plate, this allows the film to be drawn out of the cart without scratching the emulsion or the base.
