They did a nice job of explaining how they pulled off the first bank heist from Vegas using flash paper leaving no trace. But they didn't explain how they would have ignited said flash paper. Something would have been left behind, disproving their "magic". No?

Last movie watched: House by the River (5/10)
Not if a lighter was held up to the flash paper. But you're right, we don't know exactly how it was ignited.
shareBut what was the point of burning it? So the counterfeit would not get circulated?
shareThe point of burning it was to make it look like they actually robbed the bank using magic.

My thing about that robbery, why even admit to it? Why leave the card and make it a part of a big show? You just stole 3 million dollar and got completely away with it!
shareThe way I rationalized it was Dylan Rhodes had been planning every meticulous detail to this caper for a long time and as good a job as he did putting this team together, he couldn't leave to chance that EVERYTHING would fall into place on its own. Since he was FBI in the Vegas office (likely also part of his plan), he knew that this high profile case would fall right into his lap, therefore giving him the "power" to control what direction the investigation went in. First time watching the scene after they were arrested in Vegas, Dylan talking to the Horsemen felt like an interrogation. After watching it again, it felt more like a "yearly review" to see how his pawns were progressing.
shareSure they explained it - the paper was coated in fertilizer, and when the billionaire friend of M's walked up to it, the radio transmitter in his lapel pin set off the igniter in the metal strip...
I may have fallen asleep watching the movie and woken back up during a James Bond movie. I'm not sure.

Philo's Law: To learn from your mistakes, you have to realize you're making mistakes.
An even bigger loophole is the assumption that a bank vault wouldn't have a sprinkler system.
That aside, chemistry dictates that flash paper would leave some powder behind, just not the thick noticeable ash associated with burning paper.
THAT much flash paper in the real world WOULD leave some residue, but flash paper burns up surprisingly completely
A typical flash paper sheet will generate only the faintest wisp of ash
It's not that big a stretch to imagine "next level" flash paper that leaves no residue at all.
