Jake Wulf is a gifted 9-year-old boy from Odebolt, Iowa who has but one weakness: he can't remember to lower the toilet seat after he's done.
Tired of his mom getting mad at him, he decided to invent the Privy Prop, a foot-powered lever sort of like the one you see for trash cans:
It was during a visit to a doctor's office that Jake's idea for the "Privy Prop" began to take shape.
He noticed the lid to a small trash can, which opened and closed with a foot-powered lever. He went home and told his parents that he wanted to design a similar device for the toilet. [...]
Jake built plywood base and then cut thin pieces of steel and fashioned a teeter-totter at the bottom. You step on it and the seats raises. You step off and it closes.
