This appears to be a version of "The Works Bomb". Essentially a 2 L PET
soda bottle with 6 or so balls of aluminum foil and either acid (Works
Toilet Cleaner, 25% HCl) or Draino (NaOH and Al). After capping the bottle
and shaking once, the bottle will expand and burst in about 90 seconds. Our
experiments with it showed corrosive debris randomly scattered out to about
7 meters. The sound level at 3 meters was around 120 dB.
These devices are considered IED's in California, and other states, and
making one is a felony.

awry. This is from Australia...
