This is a very impressively designed LEGO Great Ball Contraption (GBC) module built by Youtuber NDL-GBC featuring minifigs shootings the balls like basketballs thanks to their spring legs — real LEGO minifig pieces that were made in the early 2000’s for basketball themed sets. Very clever, and about 90% of the shots actually make in the basket too. For reference, when I played basketball in middle school I only made two out of fourteen shots in a game, and one of those was in my team’s own hoop. I was just so excited to get a rebound I wasn’t thinking. “He pooped his pants when he realized what he’d done.” Mom! “What?” That was a soccer goal, and it was just pee.
