The Beach Glass is designed to address one very specific problem: drinking on a beach without accidentally knocking over your glass, or seeing it sink to the bottom of the sea. The glass is actually plastic, so it floats. And instead of ending in a foot, the bottom of this glass is a spike. When you’re done with a sip, drive your glass into the sand. The designers also suggest using it with snow or while soaking in a bathtub, since it will remain upright in water. I suspect that it could also be a crude weapon if sharpened into a shank.
