It's a Goldberg connection device.
The ball of the other device enters the funnel and spins round and round, reducing time and speed, and the ball drops at a constant speed to activate the other device.
'Whirlpool tower' Principle of Science
Gravity : The force by which objects on the earth are drawn toward the center of the earth.
Inertia : The force by which objects on the earth are drawn toward the center of the earth.
Potential energy by gravity : The property of an object trying to continue in a state of stationary or constant motion unless it is subject to external forces.
Centrifugal force : The force that acts from the center to the outside when an object performs a circular motion.
1 step. Make a tower leg
① Fold the four tower legs along the fold line.
2 step. Connect tower leg
① Fold the funnel fixture along the fold line.
Snap the tower leg against the edge of the funnel fixture and secure it with the snap button.
Secure two snap buttons to one tower leg.
3 step. Complete the Whirlpool Tower
① Fold the leg fixture along the fold line.
② Insert the leg fixture into the tower leg grooves.
③ Insert the funnel into the funnel fixture.
4 step. Operate the whirlpool tower
① When connecting the Goldberg device, it can be used while adjusting the height of the whirlpool tower according to the conditions.
② Install a cup car under the whirlpool tower, put marbles in a funnel and observe.
The marbles generate centrifugal force through the funnel. Because of the centrifugal force,
it does not fall directly into the hole but falls round and round.
