Sandy's Teleporter is a teleporter that was used by Sandy to hide her nuts back in Texas without leaving the lab. It appears in "Perfect Chemistry."
It looks like a brown tree log standing on a wooden stand, with a large hole cut in the middle of it. It has a light bulb on the top which flashes, and three long navy-blue tubes coming from the bark.
It is shown in "Perfect Chemistry," when Sandy shows SpongeBob this invention.
