Can't we just accept that some kids do cool stuff that many adults can't even think of? Note that this kid was distinguished in a competition for STEM projects by kids, so he's not unique, but that doesn't reduce the fact that he's uncommon to say the least.

I'm trying to think of what I did when I was 14 that was as cool as that and I can't. I had an imagination and I created stuff all the time, but nothing I'd brag about today. The Space Pistol with Disintegrator Ray was only a prototype that I never managed to really put into production.
