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.

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.

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…

ConclusionsThis 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
