I have just seen an advert from Bushwear for a tube to go in the top of an upright fridge to hang deer.

If you have a reasonable modern fridge which runs on a gas called R600a which is butane and it does not have a radiator on the back or underneath DO NOT drill holes in the sides because the manufacturers have started to put the cooling coil into the side of the fridges and you will drill through the pipes and might cause a fire and explosion.
