2. The marble sets off the mouse trap
The mouse trap sets the hammer
The hammer releases the weight tied to the elastic tension
The counter weight is lifted by the release, and the goal is accomplished

5. Conclusion
This project had many trial and errors to it. After 3 days of work, we finally found an idea that worked
Problems included:
Counter weight not large enough
Rubber Bands Break
Motor didn’t have enough power
Construction not reinforced enough
Finding Time we were all available to work
Weight bouncing back after release
Overall a great learning experience, despite the stress…
Too much Elastic Energy is DANGEROUS
Lighters are great cutting tools
More than one plan of ideas is necessary
