Pop Top Anatomy
Each pop top has a top, smooth side and a bottom, bent side.
There are two holes, one with smooth edges and another with a jagged edge where the pop top broke off from the can. Sometimes you will need to hold your pop top horizontally so that there is a right hole and a left hole. Other times you will need to hold it vertically so that there is a top hole and a bottom hole. The aluminum piece that separates the two holes is called the midsection.
Pop tops occasionally have sharp edges. Before using, carefully inspect all pop tops and recycle those that might scratch or poke.
