How to turn a plastic bottle into a cup without using glue, tape or nails

Without using glue, tape, nails or any other thing, you can get a cup from a plastic bottle. With the help of a knife, cut the bottom of the bottle, which will correspond to the bottom of the cup, and then the handle is formed by cutting a longer piece from the side of the bottle and fixing it to the base. The handle will help you hang the cup and handle it more easily. This type of creation should be proposed in primary schools, showing children how to be creative and transform objects as well as educating them to recycle.
