What happens

Homer, Bart, Lisa, Marge and Maggie sit together on a red couch in a pink living room, with Homer in a white shirt and blue jeans on the left and Maggie holding a pacifier in a blue bow on Marge's lap at the right. Homer, in a blue suit with a grey tie, stands beside a draped white sheet over a box-like object, then steps forward and lifts the sheet to reveal a homemade machine of wooden crates, a blue cylinder with a hose, and a green oscilloscope-style screen. The family gathers around the gadget as a labeled wooden box reading PATENT NO 214 68 767 sits in front, and a green and a red light glow on the device while the family watches with wide eyes.
