I fully accept that, my good man, but you still haven't told me how that little pop could have blown a hole in the mobo AND the table underneath.
I don't profess to be an explosives expert, but I have done a few crazy things as a kid and the products of the explosion always follow the path of least resistance. I used to set off matchbox bombs that were taped inside a sealed tin that was one third filled with fuel, by means of an air rifle from a safe distance. The bang was...well...quite something. The surface upon which the charge rested was scorched, but undamaged even though the tin was shredded and the lid could not be found. So what I'm saying is, you've got a charge resting on a laminated surface (mobo plus table) and the only resistance it has is the chip itself. The chip goes up, which is understandable, but there's no way a little pop like that can blow a hole through a mobo and a table so precisely, especially when the main blast escapes vertically in the path of least resistance.
