2. The Mouse Deathtrap Volume Control • Step 1: Turn the key triggering the Mouse Deathtrap (razorblade mousetrap). • Step 2: The Mouse Deathtrap releases a string that drops a pin releasing a marble. • Step 3: The marble goes through a length of small tubing. • Step 4: The marble collides with dominoes at the end of the tubing. • Step 5: The dominoes fall onto each other and trip another mousetrap. • Step 6: The mousetrap is connected to a rod that raises the volume of the speakers.

3. Stored Energy • In Step 1: There is torque in the turning of the key. • Step 2: There is tension in the string and the pin drops due to gravity which releases the marble. • Step3: The potential energy in the marble is converted to kinetic as it begins to go through the tubing. • Step 4: An elastic collision occurs between the marble and the first domino resulting in the marble bouncing back into tubing. • Step 5: Dominos are pushed beyond center of mass and create inelastic collisions as each one falls into the next. • Step 6: Rotational kinetic energy, torque, and rotational velocity turns up the volume on the speaker.

4. Complications • Setting up the deathtrap with razor blade. • Setting off the deathtrap by using key. • Marble release and getting stuck in initial pvc piping. • Adjusting height of impact from marble to domino. • Finding way to turn up volume with rod. • Injuries…

5. Conclusions This project helped with: • Team work experience. • Problem solving and troubleshooting. • Learning about construction and design. • Making an interesting way to turn up volume! • First Aid
