This is interesting, right?

But still a lot of losses. Table is shaking (moves even me), lever is bending (too heavy pendulum). Sometimes we just need to follow the instruction... At least now we know why.

Next video #7 - thicker lever with 10kg pendulum.

Current setup will have first pendulum back on.

New setup for heavier pendulums (up to 20kg maybe. Will see...)

For the hacksaw experiment - estimate is that we need 10kg pendulum by doing some measurement of a hand force when doing it manually
