"To Military Engineer 1st class Alymov

According to our information, the Swedish army is producing a new method of fighting tanks, which consists of 100 parts bicarbonate, 100 parts sulphide base, and 1 part acid. The result is a dense mass, which is put in an air-tight bottle. When the bottle is thrown against a tank and ruptures, the mass increases in volume 500 times and plugs all holes in the tank, rendering the tank crew blind.
I ask for you opinion on this subject.
