It refers to a type of ice cube shaped like a small cylinder with a hollow center, resembling a bullet. These ice forms are typically produced by specialized ice makers designed for rapid and efficient chilling. The cylindrical shape, with its hollow core, provides a greater surface area compared to traditional cubes, facilitating faster cooling of beverages. As an example, it’s often found in countertop ice makers marketed for home or office use, designed for quick ice production.
The appeal stems from its rapid cooling capabilities and ease of chewing, making it a preferred choice for many users. The distinctive shape not only cools drinks quickly but also tends to be softer and less dense than traditional ice cubes, reducing the risk of dental damage. Historically, this type of ice became popular as compact ice makers became more affordable and accessible to consumers seeking a convenient way to produce ice at home.
