How much solvent did this guy use?
I mean surely to blow up a flat you're talking buckets of the stuff.
Unless it formed a highly flammable gas inside the mattress?
A German man has blown up his flat while trying to mend an inflatable mattress, local fire officials say.
The man from the western city of Dusseldorf used car tyre solvent to repair a hole and left it overnight.
But when he tried to inflate the mattress the next day, it was ignited by a spark from an electric air pump.
"The apartment looked devastated," Spiegel Online quoted a fire brigade spokesman as saying.
The paper said the cost of the damage was estimated at 20,000 euros (£17,200), and that the man would be put under investigation for causing an explosion through negligence.
