Now this unique looking glass is definitely a hoot – and it costs only $11.99. The Half Full Optimist’s Glass says it as it is, with it offering far less storage space for your favorite drink than a regular glass, although whatever you’re going to drink is in the upper half as always. I guess that’s the only way a design like this can work since it guarantees a half full glass every single time you top it up. At least it is not located at the bottom so that you end up being a pessimist instead, using this opportunity to drown your sorrows even more. A half-full optimist – I like the sound of that.
