Each until recently did not believe that it is possible

From the author:
Shown in the example. Used to think that this is nothing there)





In fact, the idea with a toothpick on a toothpick - was spontaneous, and I do not think that happens. But it turned out that the thickness of a toothpick in the place where it rests on another - quite enough (of course taking into account that you are doing it very carefully and kept the balance).



Left the heavy elements (teeth themselves), right - the hard part, for which we hold the plug. Right in the center axis spend where are toothpicks, weight, and with one and the same on the other side :)
(I certainly did not measure, but once it is in balance - meaning the same, you can not argue with physics)
