2. Steps A pin is pulled releasing a projectile.
The projectile hits a target on one end of an axle.
The opposite end of the axle triggers another, similar axle.
Smaller axle knocks a ball into a tube.
The ball collides with a ball of identical mass at the bottom of the tube.
Both balls roll on an open PVC pipe and then
fall into a catcher attached to the bottom of a banner displaying UT spirit.
collide with Step 1 of the next group’s device.

3. Concepts Trajectory: pin releases key chain
Conservation of angular momentum: axles rotate
Conservation of energy: golf ball rolls down tube
Collision: golf ball hits second golf ball
Torque: banner opens

6. Creativity was necessary to navigate a low budget and various technical difficulties
Team work and good attitudes were crucial to success
Applying the concepts is not always easy but very do-able and fun!
