Made of sturdy weighted glass, this multi-use Blue Optical Drinking Cup creates a charming light spectacle. Clear glass with a blue painted bottom creates a beautiful optical illusion when held at different angles. At certain angles of light, the cup appears mostly clear with a colored bottom. Simply twisting the cup at a certain angle will create a colorful optical illusion. Holding 6 ounces, this cup will work beautifully as an espresso, whiskey, or gin cup.
