MARBLE TWISTER
| Demo Number | 056 |

| Description | Marbles, racing down the interior of the Marble Twister, will increase both their speed and their ability to “hug” the inside tracks made by the wires as the spirals become tighter. Marbles decrease their speed when tracks become wider.
The spiraling wire path of the Marble Twister prevents the speeding marbles from being propelled outward in a straight line, forcing them into a curve and giving us the illusion that they are somehow defying gravity – which, in fact, they are not. |
