Planetary Glass Set
On top of their sweet swirly interpretations of what our solar system would look like if it were made of heat-wrapped glass and sized for juice drinking and candle burning, two things are cool about ThinkGeek's Planetary Glass set: 1) It includes the sun and Pluto; and 2) The sun glass is bigger than the other planets and the Pluto glass is smaller. So when you're in a group it will be easy to designate who the fun revolves around and who should be kicked out because they don't really belong there.
The set of 10 Planetary Glasses includes the 8 MVEMJSUN planets, each holding 10 ounces of liquid, plus a 16-ounce sun and 4-ounce Pluto. Despite being draped in high-temperature heat wrap designs, the glasses are not suitable for the microwave, dishwasher, or drinking OJ in space.
