It's been a while since my last video! Part of this was trying to get this design to work (spoiler alert: I wasn't able to), part was because the school year started and I got back to my normal, busy teacher routine, and part was because I felt like I had failed in this and wasn't especially anxious to post that.


Ultimately, I think the problem boils down to materials. To get better results, I should have used rigid walls. Rigid walls that you can see through are going to add expense, rigid walls that you can't see through make for a crummy video.

Also, a denser material for the weights would have worked better. Planning ahead for materials, I calculated how sensitive the device would need to be in order to get a noticeable shift when I put the weights nearby. Because the weights are not made of especially dense materials, the center-to-center distance between the masses was larger than I'd have liked, meaning the gravitational forces were smaller and the device needed to be more sensitive. Making the device more sensitive means that any little air currents are going to cause more noticeable errors as well (which made the whole thing unusable).

I recognize that part of conducting a science experiment is not claiming conclusive results unless you have reason to be highly confident in the experimental data. That being said, it sucked to work on this for so long and not get anything I could use from the experiment.

I'll be working on some smaller-scale videos in the near future; things I know I can get to work the way I want them to. If you've been with me for a while on this project: thanks for coming along. I have ideas for the next version of this project, but I'm not sure when exactly that will be.
