Objective: Making Susan pop the balloon. The Device Constructed entirely from scraps. Uses several different energy conversion processes. Performs three distinct task in order to achieve the objective. Simple construction and reliable results. Minimal Cost involved. Combination of every team members ideas.

Velocity Calculations From the start… A metal ball starts from rest and is released by hand down a ramp. The ball’s velocity is calculated by: Known Dimensions: Height of ramp- 16 inches. Weight of ball- 2.4 ounces mgh = .5mv^2 (2.4oz)(1lb/16oz)(32.2 ft/s^2)(16 in.) (1ft/12in) = .5(2.4oz/16oz)/32.2 ft/s^2 (v^2) Velocity = 9.27 ft/s

Device function From release of the metal ball, the ball travels down a ramp. Momentum launches the ball from the end of the ramp where it hits a plank of wood. The plank of wood is a clothes pin which releases a string holding a weight. When the weight is released, a pulley system is activated and reveals Susan! Susan is rapidly pulled upwards and drives a nail through a balloon.

Conclusions: …to the end. POP! In conclusion, we are very satisfied with how our Rube Goldberg device turned out. Everyone added their own ideas to make the device a success It took very little time to complete the entire device (about 3 hours). This project was much more fun to do than EF homework. POP!
