Can this really happen?

Question

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

Answer 1

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

People do stuff like this

Answer 2

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.
