Watch the video. This is one of those things you kind of have to see happen to understand.
A so-called “stick bomb,” “frame bomb,” or (worst of all) “xyloexplosive device” (Wikipedia) is an arrangement of flat flexible beams, like popsicle sticks or tongue depressors, that are woven together under tension such that they can be “set off” at one point and sort of explosively disassemble starting at that point, with the reaction propagating away along the structure. Like domino toppling, but flashier.
The problem is all of the common names for this trick would probably get you strip-searched if you used them at the airport.
TSA AGENT: “What are you doing with all these popsicle sticks?”
STICKBOMBER: “I’m going to a stick-bomb convention. I mean, I use them to build frame bombs. Haven’t you ever heard of a xyloexplosive device?”
TSA AGENT: “Kindly put your hands in the air and step over here with me, sir. Don’t make any sudden moves.”
I’m not sure I have any better suggestions. But perhaps we can all brainstorm. “Poptomata?” “Spring-frames?” Anyone?
