I have a similar story from 2001, 8th grade science fair.
One of the kids had a seismograph (parents) one had some bacteria thing (probably also parents, that kid was as dumb as the contents of his petri dishes) they all looked super professional and stuff and were obviously shit from books or the internet.
I fucked around for weeks in class doing basically nothing and the night before threw together a hand written display with some info I looked up, painted a balloon and pvc pipe with paint, and stuck it on. The “project” was about the impact of static on heavy machinery and the idea of applying an insulating coating to reduce static buildup and transference on machine parts, displayed via balloon, pipe, and latex paint. Totally original idea (to me, anyway) and research and they thought it was great even tho it looked like complete shit.
I have these for all my chargeable things. Bought like 4 packs with multiple port types, so I have tons of extra cables in case some die. They are great for game controllers, phones, tablets, rechargeable keyboards, and all sorts of other shit. All you need is multiple ends, and you can use the same cables for everything. It’s glorious if you have a mix of port types.
