Oklahoma City, Okla. ARTICLE SNIPPET: "Dreyling told authorities he had made the device and said it was basically a pipe bomb, according to an affidavit. Dreyling said he built the device for entertainment value, never intending to hurt anyone, and forgot that it was in his carryon bag when he brought it to the airport, the affidavit said.
Dreyling said he learned as a teenager how to build homemade explosives from Web sites like The Anarchists Cook Book. Dreyling said he has built and detonated several explosive devices for recreational purposes, according to the affidavit.
He also told authorities he had a bag of gunpowder, an empty carbon dioxide cartridge, and several ignitors in his Norman residence, according to the affidavit."
