After the presentations, people who didn't test yet had a chance to test how well their amps amplified.
The tests saw a few failures, however Lisa's passive amplifier set the class record, amplifying sound by 10 decibels. Congratulations Lisa.
After having finished the tests, students were able to test out everybody's amplifiers.
The students then watched a video, about badly designed doors, called norman doors, and how designs should make it so the user doesn't have to think about how the item works.
