They Used a Bottle Cap as a Heat Sink
This Raspberry Pi single-board computer is a tech support worker’s worst nightmare. The owner actually used a bottle cap as a heat sink for the processor, which is pointless because Raspberry boards generally stay cool unless they are overclocked or over-processed. Alright, so maybe it’s not the worst idea but there are certainly safer options out there. Just ask any professional. They’ll know what to do.
