I saw an interesting image image, would it fall down or stay in stationary?

    Try it! But make sure your feet are safely away. – NickD Mar 17 '17 at 18:59

  • Famously, if you stack $N$ dominoes you can achieve approximately $\ln N$ overhang without the centre of mass going past the edge. – J.G. Mar 17 '17 at 23:25

Yes it's real, try it. The centre of mass is aprox under the pivot point

People do stuff like this

Read this article about it from Scientific American

Essentially:

If you place a large enough person on the shorter end of [a] seesaw, that person's weight will apply more net torque to that end, suspending the lighter end of the seesaw in the air. The head of [this] hammer performs a very similar function, but instead of pushing down on the shorter end of the seesaw like the weight of a child would, the gravity acting on the hammer's center of mass pulls on the ... tip of [the stick] from below the table.

But yes, it's pretty easy to set something like that up.
