Usually the game ‘Fetch’ is played with a human and their dog. An object such as a ball or a stick is used in the game. The human usually launches the object a certain distance from the animal and then the animal goes and retrieves it and brings it back. Very rarely cats have been known to dabble and engage in this fetching behavior.
In the video below, an engineer has constructed a fetching machine for his pup. The apparatus works like this, the dog drops the ball into a slot. The dog then runs over to a wood 2×4 and starts pressing down on it like a lever. Eventually enough force is placed on the wood stick that the ball shoots out from the slot and flies into the distance.
The dog runs, fetches, and brings the ball back to the place it first dropped it. Some may say this human is lazy and should just play fetch with his dog. But as the old saying goes, work smarter not harder. That motto usually goes a long way when it comes to engineering and physics.
This pup seems so satisfied with his new toy, I think he will be enjoying this for years to come! 🙂
