We walk outside into the Science Park. Out here we see a dump truck. Two people can sit on it as it rises. The riders will stay at the top until gravity overcomes friction and the rider will slide down. There is also a car on a pulley that can be lifted from one of two ropes. If we climb up 34 steps, we run into what's probably the Science Park's most popular attraction the High Wire Cycle that allows riders to safety bike several stories above the ground.
