London Bombs

These guys were definitely out to make major mayhem.

"When you put the X-ray machine on it [the bomb], you see what is bulging on the sides of the bottle are nails — many, many nails," said Ayers, while examining the photo. "And the nails are put there so that when the bomb goes off, the nails will tear tissue and kill people in the area. Bombs don't kill by concussion. Small bombs, they kill by the blast effects of fragments of glass or metal, and this is designed to kill people."

Charming.
