This is a display vessel that makes use of electrolysis bubbles in beverages. Conventional bubble displays require moving parts because it is common to use air taken from outside of the water to represent pixels. However, it is difficult to increase the number of pixels at a low cost. BubBowl has designed a liquid-surface display using pixels of bubble clusters generated from electrolysis. The cup-like BubBowl device generates a 10×10 pixel dot matrix pattern on the surface of a beverage.

Masashi Kawamura: “A smart and affordable way to create bubble displays. I can easily think of fun ways to use this mechanism for advertising.”
