Bubble creator

The bubble creator was built by Finn in the epiosode The Real You after he equipped the Glasses of Nerdicon. It has the ability to make bubbles ranging from the first dimension to the fourth dimension. However, the fourth dimensional bubble is totally incomprehensable by 3rd dimensional beings such as the residents of the Land of Ooo. The bubble, being an entire dimension greater than its host dimension, colapses, forming a black hole. Finn impales the bubble creator with his sword, and jams it, and himself into the black hole, destroying both the creator and the black hole, but saving himself and the Candy Kingdom.
