A soda-can opener is a device used to open cans of soda. It typically consists of three parts: a TAB, a poptop, and a pulltab. A TAB is a small metal piece that is inserted into the can and twisted to open it. A poptop is a type of can opener that uses a lever to open the can. Finally, a pulltab is a type of can opener that uses a handle to open the can. All three types of soda-can openers are designed to make opening cans of soda quick and easy.
