So there was this crackling spray of blue sparks through the air and steady plumes of thick smoke. Stopped the van and ran round to the back. The van is full of stacks of chairs that are LIVE. So we don't touch them except with a pole with a rubber handle: more arching bright white light. And chair legs glowing red hot on fire. Mutual perplexed laughter. (with of course a due appreciation of the potential seriousness of the situation*)

Ripped out the van fuses, and tried to see through the no torches darkness to the battery wires. But still the blue cracking jumping current in the chairs.
Manage to disconnect chair stacks from eachother by hitting them with pole, and using a hoody as a rope to drag them crashing into the middle of the night residential street. Cooling and no more sparking is good. Oh the potential of dissimilar metals connected; and the burning heat of rapid oxidation.

Chemistry inspires me.
