Foolproof Dartboard

Rocket scientist Mark Rober and his pal spent about 3 years perfecting their invention. This motorized dartboard is designed to track a dart being thrown at it, and ensures a bulls-eye assuming you’re somewhere within its board. It also can make you miss every time

You’d think that after 3 years of just practicing, he’d be able to hit a bullseye naturally. But still really cool!
