A sand pendulum that creates a beautiful pattern only by its movement.
But why does the ellipse change shape?
The pattern gets smaller because energy is not conserved (and in fact decreases) in the system. The mass in the pendulum gets smaller and the center of mass lowers as a function of time. Easy as that, an amazing pattern arises through the laws of physics.

IF YOU DONT REBLOG, YOU DONT HAVE A HEART.
im sorry followers.
Midnightwhoree: How could i ignore this! Always and forever against child abuse!
People who abuse children are sick! && should be locked up!
Reblogging because my father was abusive to my family. And it was the most horrorfying thing ever…. my mother, my sisters and I suffered a lot because of him.
… I had another thought relating to Sigmar playing dad to Lorgar. As in like, proper crossover.
Gelt: My lord, about the boy– Sigmar: Yes! A remarkable child. And already in fighting shape, too! They grow up so fast, don’t they? Gelt: Not like that they don’t. Sigmar: No? Are growth spurts not common in this age? Gelt: Yes, they are. But the boy is nearly as tall as we are, my lord. Sigmar: And? Gelt: He is eight. Sigmar: … Yes?
He’s forgotten many things.
