In 2016, former NASA engineer Mark Rober and The Backyard Scientist filled up a backyard swimming pool with 25 million Orbeez water balls. On that same day, Rober decided he was going to fulfill his childhood dream of creating the world’s biggest JELL-O swimming pool. With the help of his brother, Rober accomplished his long-awaited goal and attempted to go for a swim in it.
