Exploratorium demos experiment with motorcycle

SAN FRANCISCO

The historic hands on museum reopened on San Francisco's waterfront, where it's getting rave reviews and two and a half times more visitors than at the old building in the Palace of Fine Arts.

ABC7 is the Exploratorium's official T.V. partner. This Sunday, Oct. 20th at 6:30 p.m., ABC7 News Anchor Dan Ashley hosts a special half-hour program about what's got visitors coming back for more.

We have a preview of one of the fascinating spectacles you are unlikely to see anywhere else. It involves a 300 pound block of ice, some very thin wire and a motorcycle.

The plan is to cut the block of ice in half, but have it remain whole. It's a crazy demonstration of a physics principle called regelation, the same phenomena that makes giant glaciers move slowly forward.
