How do you have fun when its raining hard outside, and the world has turned gray? Confined inside the flat, I pottered around until I discovered some tops and a small glazed bowl. The photo here shows the state of confinement of tops inside a small space. In physics there is a notion that protons are made of quarks which can never break out of the proton; this is also called confinement. There you have confinement in a nutshell. Did I just quote Hamlet?
Whatever. Sweet dreams.
