This device uses inertia and gravity to connect marbles to other devices.
Corrugated cardboard, Plastic, etc.
Switch body, Switch guard rail, Snap button, First slope board, Second slope board, Switch support,
Hoop fixing board, Hoop wheel, Switch, middle Rail, middle Rail guard
If a ball from another device falls into the hoop, the hoop rolls, dropping the ball into the groove in the middle rail.
The ball rolls over the middle rail and activates another device.
It can be used between an F-3 rubber car and an F-5 domino and can also be used in other devices, depending on the situation.
'Hoop rail' Principle of Science
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.
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.
1 step. Make a hoop
① Fold the hoop retaining board along the fold line as shown in the illustration.
② Fit the hoop fixing board into the groove on the hoop wheel.
③ Fold the hook into the groove of the wheel and fasten it with a snap button.
2&3 step. Make the first rail and the second rail
①Fold the first rail along the fold line and secure it with a snap button.
① Fold the second rail along the fold line and secure it with a snap button.
4 step. Make a middle rail
① Fold the middle rail along the fold line and fix it with snap button.
② Assemble the rail guard into the middle rail groove.
5 step. Make a switch
① Fold the switch body and switch support along the fold line.
② Fit the switch into the groove in the body as shown in the picture.
③ Assemble the switch support into the groove under the body.
6 step. Make a hoop rails
① Install the intermediate rail between the first rail and the second rail as shown.
② When rolling the hoop, check that the groove of the hoop fits into the middle rail.
Then lay over the first rail groove.
③ Install the switch next to the hoop.
④ Lift up the switch installed on the switch body and align the marbles with the grooves.
7 step. Operating Hoop Rails
① Touch the dominoes.
*The hoop is rolled onto the second rail and the marbles is lowered to the intermediate rail to activate the next connector.
② The switch is activated so that the marbles enter the hoops on the switch rails.
③ As the marbles falls, the hoop rolls, dropping the bead onto the middle rail.
