A) While building the final catapult part we had to alter what causes it to launch, we had to change from a string pulling and launching to, a different mechanism that is actually strong enough to pull it. When making the plinko machine, giving a wood post to stop the marble from falling out. Since we couldn't hold up the fan we wanted at the end of the plinko machine we had to string it up and hot glue it with the end of the ramp with the marble.
B) Making the marble actually go through the entire plinko without it flying out or hitting a screw and missing the fan. Building a funnel system that it good enough to take a lot of time out. Finding a sufficient way to launch the golf ball.
C) Kinematics, finding a good angle to launch the ball to the certain lengths on the ground, in actually predicting how the golf ball can output the amount of force needed to launch it far enough. The water moving through the funnel and tube, shows the water moving through and taking the shape of the container it is in.
