plankton invents the machine in "It Came from Goo Lagoon." It is used to open the crack at the bottom of Goo Lagoon to release a Giant Super Goo Bubble. It is then used agin, to control the bubble.

According to Plankton, its actual purpose is to open things as easy as a clam.

Plankton's plan was to use the bubble to threaten Mr. Krabs into giving Plankton the Krabby Patty Secret formula because according to Sandy, the Super Goo is toxic and can destroy things. Plankton nearly succeeds with getting the formula, but it is just a stick of dynamite rolled in a piece of paper as a trick. Once he gets the fake formula, before knowing it was fake, he goes against his deal with Mr. Krabs and pops the bubble, however, the super goo did not destroy things, but instead just covered the town and its inhabitants in the goo.

It was destroyed when it hit the roof of the Chum Bucket after the dynamite went off.
