The Tilt Glass Indicates a Volume of 6 Ounces by Leaning to One Side

The Tilt Glass is unlike many of the topsy-turvy tumblers that you might have come across; its quirky crookedness is practical and not simply aesthetic. Designed by Markus Johansson, this drinking vessel's form is actually capable of measuring a fairly precise serving of alcohol.

An empty Tilt Glass sits with its inner base fairly level, flaunting its eccentric curving contours and its angled rim. As you carefully pour a beverage into it, the drinking glass will not budge, until you reach a volume of 6 oz. When this occurs, the whiskey glass will become off-balanced and shift its weight onto the beveled part of its bottom. This change produces a ringing noise that even allows blind bourbon lovers to prepare a standard portion.
