Re: "what we do with it is our fault"

Nod, I remember (spoiler alert) literally doing that.
In the task following a demonstration where a large capacitor could be made to briefly flash a mains bulb from a small battery, we ran out of switches.
"Don't worry", said my lab partner, "this morse code tapping key I've spotted will suffice".
Shaking off a large jolt from accidentally touching it mid-experiment I shook myself and warned "be careful, it tickles a bit".
"Wimp!", said the other boy ... and promptly jumped six feet in the air when he ended up doing the same!
// The teacher's name? Newton. Thanks to also having a Mr Poulton he was occasionally known as Neutron (and Proton, respectively - as physics and chemistry teachers, the "nucleus of the science department" *groan*) but mostly we called him Isaac :)
