Everyone gets random ideas that sound cool but they never go through with them. Well, this is not the case for Mark Rober who is a former NASA engineer. Once he gets a crazy idea, he spends months planning his every move to make that idea come to life and his latest idea was to create a pool full of jell-o! Yes, you read that right. Mark wanted to fulfill his childhood dream of belly flopping in a jell-o filled pool.
