Sodium benzoate and Potassium chlorate whistle mix(reaction test) HD

A typical whistle mix is made from 70% potassium perchlorate and 30% sodium benzoate, measured by weight. The fuel in most whistle compositions is a salt of an aromatic hydrocarbon. Compositions with chlorates and gallates were used historically, but have now been abandoned as prone to accidental ignition. Whistle compositions tend to be particularly sensitive. To achieve the whistling behavior, the composition must be formed into a solid grain; it otherwise burns too rapidly and just explodes. The composition is typically compressed using an arbor or hydraulic press. Ramming with a mallet (which is acceptable for many other compositions) may result in an explosion. potassium chlorate yay- please subscribe :) for safety i did not compress the mixture.
