Now that we had our idea or the beginning and supplies we started building we thought it would be easier to build and than sketch so if something didn’t work out we could change it and not keep redrawing it. So we put the domino’s on the ping pong table and put the tennis ball in front of it and thought we should have the ball go though something so it could narrow down and hit something else. Now that we got that built we thought that by now the tennis ball would loose speed so we taped drum sticks down to the ground and put a foose ball down on the beginning of the drums so when the tennis ball hit it the foose ball will go into a tube on the mat. So when we got that we were half way though with our Rube Goldberg and stopped there.
