the device included two liquid-filled canisters liquid, wires, and a digital clock.
if really just a “discarded school science project” then (nine’ll get ya a tater) it’s a DIY electrolytic battery. y’know, iron or zinc plus copper in salt water ganged up to make a few volts demonstrated by the clock.
(and not the sort of scary mischief we kids 12,000 years ago got up to with nitric acid and iodine crystals, hydrochloric acid and aluminum… hydrogen peroxide etc (we really shoulda died))

As someone who collected magnesium scraps from science classroom floors along with his friends: I agree.

Didn’t this happen a few years ago in Texas? The student built a digital clock, the school had him arrested?

We were actively encouraged to do that one by the chem teacher (who had us put it in bottle caps, and set it on the nearby street to dry…).
Nobody lost any fingers, and the teacher didn’t get fired, so go figure…

At least there were canisters of liquid. Unlike the ATHF LED sign bomb scare.
