A park ranger needs to build a zipline to drop food supplies to her mentor park ranger at the bottom of a gorge. Unfortunately, she does not have the instructions to build the zipline according to the proper specifications. Without directions, she is unsure of the correct angles to attach her zipline to each tree. Additionally, she needs to figure out how to open the chute to drop the food supplies.  Challenge: Create a zip line that will release from her bucket (paper cup) the food supplies (represented by a marble) onto the target (placed 5/8 of the way down the zipline)  before the gear reaches the opposite end of the zip line.
