I've never dared mess with this myself, but hobbyists report that it
happens all the time: the slightest electrostatic discharge is extremely
dangerous. The (partial?) cure is soapy water inside so it coats rather
than beading up. But I've also heard about one spontaneous explosion
inside a closed acrylic electrolysis cell.
I first heard about this around 1992 from a story of crazed teenagers
setting off a packed row of five (seven?) garbage bags of home made H2+air
on Halloween night. They triggered them via high voltage and radio
control from a cheap RC toy car. They used soapy water to avoid getting
killed. One part of the story was odd: they said they only had to spark
the end bag, then all of them exploded.
Isn't UV light supposed to trigger explosions in hydrogen+chlorine mixtures?
