P.K.E. meter
The P. K. E. meter is a tiny device that the Ghostbusters use to track ghosts. It’s like a dog tracking a smell, but it’s really just guessing.
My P. K. E. meter tracked the ghost to the fridge. It was just looking for snacks.
The meter beeped like it had a crush on the ghost.
It took my P. K. E. meter 10 minutes to realize the ghost was right behind me.
