Also maybe instead of using the circuit in the video to prank, you could use it as intruder alarm, light switch based on room light, or whatever else! It is a useful circuit. Just be careful around high voltage!

One of the great aspects of these videos is the demonstration of picking yourself up (sometimes literally) after your plan fails, figuring out why it failed, and perhaps improving the design. This resilience and willingness to change design is a pair of qualities too many students struggle to acquire. This teacher suspects (and does not mind) that you have preplanned "oopsies."

So I thought it would be cool if it was possible to make a Lazer trip sensor with like a min timer so that once you trip it, it will keep the lights on for like 1 min then shut off. I have right now a motion sensor at the top of the stairs and bottom connected in series. So any ideas how to maybe make a Lazer trip work instead??
