Is the Bullet Test Tube temperature sensitive?
Yes and no. The Bullet Test Tube was designed to be shot at normal room temperatures. This allows the Bullet Test Tube to be stored indoors with no special handling. For best results the Bullet Test Tube should be shot when its core temperature is between 68 and 76 degrees, with an optimum temperature of 72 degrees. The density of the bullet expansion material inside the Bullet Test Tube allows it to remain on the range for more than an hour in temperatures as cold as 32 or as high as 90 degrees without worry of the results being affected. The core temperature of the Bullet Test Tube can be checked with an inexpensive candy thermometer pushed to a depth of three inches inside the Bullet Test Tube.
