Self Reflection

Suppose I would give myself a mark out of 100. I would give myself 75-80 because the fan couldn’t push the lever to hit the ball down the ramp. At the time of filming, I didn’t have time to replace the fan with something else. I decided to tie a piece of dental floss around the lever to pull while the fan was on. I did check all of the lists and the machine does do what it is supposed to do, which is to turn on/off the light switch.
