That has to be the shittiest bomb I've ever seen. All the footage of scrap bombs in Iraq/Afghanistan, all the homemade pipe bombs on police seizure posts, every video game and cartoon I can think of. They clearly gathered everything in the house that seemed explosive, everything under the sink that seemed adhesive, and picked the nearest writing surface out of the trash. They have no fundamental idea of how a bomb works and they're trying to invent one with the same strategy as the apes in 2001: A Space Odyssey.
