Schrödinger's cat and quantum entanglement. The cat is inside a box, shown in both alive and ghostlyQuantum Superposition and Schrdinger's Cat Quantum superposition is a fundamental principle of quantum mechanics. It states that a quantum system can exist in multiple states simultaneously until it is measured. For example, if a particle can be in state A or state B, in quantum superposition, it can be in a combination of both states at the same time. This differs from classical systems, where an object can only be in one state at a time. A famous

Buy a longer launcher!!! I got what I paid for! A 12.2 inch launcher does not build up enough energy to throw it very far and it is tweaking my elbow. The dog is very disappointed since the ball only goes about 30 feet. I’ll keep it for small dog park use. The balls are hard and my 22 pound Cockapoo can’t get it to squeak.

The launcher works very well and will probably last forever unless your dog chews it up while bring it to you to get you to play, but the balls, well, they're not made for labs, that's for sure. That's the bad news. The good news is that worn out or abandon tennis balls fit the launcher just fine. Save your throwing arm. Do your dog(s) a favor. Buy this thing.
