curious and unusual objects

I open this new topic because I am always surprised by some things that I discovered.

For example, the Pythagorean Cup which empty completely as soon as the liquid level in the cup exceeds a certain height in the cut.

Also I just found this curious object called a rattleback : A sort of screw-top which normally rotates in one direction, as if the spear in the other, it will stop and go back the other way ...!

Look at them videos, it is surprising.
(Issuance It's not that guinea pigs]It is not as guinea pigs shows a funny video about anagyrus and in general their "Magic or scientific" sequence is very interesting).

You must have or know other surprising objects to introduce ourselves ...

Hum hum hum ... he's very doubtful air this curious object mystery! ... : Shock:
As the gentleman tester: the laws of physics seem to have been questioned ...!

Given the current needed for arc welding, I have trouble believing that with a simple little drum mower, there is enough current to arc welding!
