Most people will go their entire lives without ever knowing why soda cans have a small tab hole

For many, the soda can is a ubiquitous part of daily life, a simple vessel for delivering a refreshing beverage. Yet, few stop to consider the intricacies of its design, particularly the small hole in the tab. This seemingly insignificant feature is often overlooked, but it plays a crucial role in the functionality and user experience of the can. This article delves into the mystery of why soda cans have this small tab hole, exploring its purpose and significance in modern design.

The design of soda cans has evolved significantly since their inception. Originally, cans required a separate tool to open, known as a church key. This changed in the 1960s with the invention of the pull-tab, which allowed consumers to open cans without additional tools. Over time, the pull-tab was refined into the stay-tab design we see today, which remains attached to the can after opening. This evolution was driven by a need for convenience, safety, and environmental considerations, leading to the inclusion of the small tab hole.
