Apparently these things are becoming sufficiently common in some places that warnings have been issuedA "works" bomb is described as Drano and foil mixed inside a bottle. The chemical reaction makes a volatile build-up of gases and subsequently detonates the bottle with a great amount of force, with the chemical substance in the bottle becoming boiling liquid at that point, the e-mail said.
The explosion can be severe enough to cause second- or third-degree burns or blindness, Mansell said in the e-mail.
Draino is Sodium hydroxide (lye, caustic soda) and aluminium foil. When mixed with, water hydrogen gas is given off. the results can be quite violent - and the explosion itself is not the only problem. The reaction causes heat and when it explodes the hot, caustic liquid is sprayed everywhere. It will dissolve skin and eyes
