For those who asked about the anti-gravity hill, here is the explanation. The marble rolling down the first small hill has enough inertia to travel up the next hill about an inch and a half. Near the end of this uphill#65279; travel, the marble operates a lever, which pulls a pin out of a hole in the bottom of a thin wooden sled that rides in a tunnel below the floor of the uphill ramp. The sled, about a eighth of an inch thick, contains a strong neodymium magnet.

Men jag ser inte riktigt hur kulan kan åka uppåt på rampen. |
