Jumbonium

Jumbonium is an element large enough to be seen with the naked eye. It is also very rare and valuable, with only one atom in existence. The Jumbonium was in 3001 used for the Miss Universe competition, where it would hover above the priced tiara.

According to Bob Barker, the atom is worth 200,000 dollars or at least somewhere between 200,000 and 200,001 dollars. According to Professor Hubert J. Farnsworth, the nucleus alone is worth 150,000 dollars.
