You can't describe that feeling, as if it could spin you up into the sky. Twisting Buddha beads, tray walnuts, turning pens. They said they met their opponents.
Aidan, 13, spent weeks designing a fingertip gyro with Lego bricks. Of course, true fingertip gyroscopes can rotate longer. But when children design and build their own ideas, in the process, can they find the best way to distribute weight and reduce friction between moving parts?
Here are all the parts you need:
First, a 4 x 4 circular plate is placed at the top and bottom of the 6 x 6 circular plates. A 2 x 2 round tile with holes (smooth surface) is arranged on the shaft.
The shaft with the round tile is combined through the 6 x 6 and 4 x 4 round plates.
A 2 x 2 circular plate with holes is sheathed on the top of the shaft. You need to set aside some space so that the rotator can rotate freely.
Then we find that if we add some equipment, our rotator will rotate longer, and the extra weight seems to give the rotator more power.
Place a 2 x 3 brick under the disc, and then add a 2 x 2 brick and another 2 x 3 brick.
Finally, add all four gears and your fingertip gyroscope is complete!
Now try to spin your fingertip gyroscope!
