In this video, the creator, Mumbo, sets out to build a contraption that will launch a player (himself) as high as possible in the game Minecraft. He starts with a simple design and iteratively adds layers and modifications to increase the height he can reach. Through trial and error, Mumbo optimizes his design, overcoming issues such as timing and redstone signal strength limitations. Ultimately, he succeeds in launching himself over 33,000 blocks into the sky, hitting the game's ceiling, and calculates that he reached a speed of approximately 1,000 blocks per second.
