Do not wind the wire too tight or the tube may start to collapse. Wrap the wire around the tube, also known as turnings, until it has gone around 300 times. Make sure that the turnings are all next to each other in the order that they are wound from one side of the tube to the other. Tape the end of the wire on the toilet paper tube at the opposite site of the 4-inch wire sticking off the end of the tube. Leave four inches at this end of the tube sticking out past the tape as well.
