Michel what a neat idea! Having access to Infinite Toilet Paper would certainly be a useful thing! I like that there is a barcode located on the toilet roll dispenser which means that only certain people can have access to an infinite supply of loo roll! I wonder if the sales from your invention could be used to replant some trees which the toilet roll paper will of been made from? Therefore meaning that an infinite supply would indeed be possible! Keep on inventing and send us another idea soon!
