Rats! They ate my cables again!
Live electrical wires gnawed by rats can become exposed and cause short circuits or electrocution. Ensure that no flammable materials or gasses are within reach, and perform this experiment in a well ventilated laboratory under the care of a qualified adult. Disconnect ALL electrical connections before handling the cables. Ensure that protective gear (insulating gloves)/goggles are used. Rats should be handled with care as they bite!
