High
Wire Bicycle
|
| |
|
| Description: |
The
High Wire Bicycle rests precariously on a guide
wire suspended across an open expanse of the California
Science Center's grand atrium. As visitors mount
the bicycle for a "ride," they peer down to the
floor approximately 43 feet below. The bicycle trip
starts with the visitor riding backward out of a
controlled loading area. They ride approximately
36 feet across the atrium and return to the platform.

|
| Scientific
relevance: |
The High Wire Bicycle is an interactive exhibit
that allows visitors to experience the law of "center
of gravity" in dramatic fashion. They will learn
firsthand that any force causing the system to tip
will be offset by the force of gravity acting on
an attached counterweight.
|
| |
|
| Fun
factor: |
The
bicycle, held in place by a large counterweight,
allows visitors to test their "nerves of steel"
as they pedal across the wire.
|
| |
|
| Safety
features: |
As
the bicycle tips, the straight bar from which the
counterweight is suspended swings upwards. Gravity
pulls the counterweight back towards the ground causing
the bar to correct the bike and put it in a vertical,
stable position on top of the cable. The High Wire
Bicycle is fitted with many safety features, including
a seat harness and safety net. Visitors riding the
bicycle must be a minimum of 42 inches tall and weigh
no more than 250 pounds. |
