One trick was to make balloon bombs by filling a dustbin bag with acetylene and then poking it with a lit match. Overnight you’d hear the bang of acetylene bombs going off, followed by cheers along the paddock. Spotting somebody wandering along, half asleep, not aware of what was going on around them, you’d let off an acetylene bomb and watch them jump three feet in the air in shock. Cue: cheers.
