A cheap but effective smoke screen can be made as follows: First drill a hole into the exhaust manifold of your car, and weld the nozzle of a small plant sprayer over it. A gas line is then run from the nozzle to a pump and container containing castor oil inside the vehicle. Clouds of smoke are produced by pumping the castor oil onto the hot exhaust manifold.

(1) Speed at around 25-30 mph.

(2) Get off the gas and crank the steering wheel to the left ¼ to ½ of a full turn. At the exact same time, hit the emergency brake hard. Those of you with manual transmissions will have to depress the clutch, also.

(3) When your vehicle is at approximately 90 degrees, release the emergency brake, step on the gas, and straighten out the steering wheel. If you have a manual transmission, you will have to let the clutch back out as you are hitting the gas.

(4) Get out of the area fast.

The most interesting use of police dogs concerned scent identification, a method analyzed by Dutch and other researchers, but adapted by the unique paranoia of the Stasi. As early as 1973, the Stasi began collecting smell samples of a large number of citizens. Sometimes this was done with a special chair that the subject was asked to sit on during a visit to the police station. The chair had a dust cloth on top of the seat that was clamped into place by a removable frame. The subject had to sit in the chair for ten minutes, but after the interrogation was over, the dust cloth was removed and stored in a glass jar.

Sometimes Stasi officials did not bother with being subtle and merely told subjects to put a cloth under their armpits or even under their pants in the groin area. The cloth was carefully handled by tweezers in an effort not to allow contamination by other human scents.
