Flash powder of any formulation should not be mixed in large quantities by amateur pyrotechnicians. Beginners should start with sub-gram quantities, and refrain from making large devices. Flash powder should only be made at the site at which it will be used. Additionally, the mixture should be made immediately before use.
M-80s are an American class of large powerful firecrackers, sometimes called salutes. [1] M-80s were originally made in the mid 20th century for the U.S. military to simulate explosives or artillery fire. The "M" is designated by a U.S. military convention for "standard" equipment and "80" is for the 80 grains (5.2 grams) of flash powder within ...
Armstrong's mixture is a highly shock and friction sensitive [1] explosive. Formulations vary, but one consists of 67% potassium chlorate, 27% red phosphorus, 3% sulfur, and 3% calcium carbonate. [2] [3] It is named for Sir William Armstrong, who invented it sometime prior to 1872 for use in explosive shells. [4] [additional citation(s) needed]

A typical cherry bomb contains a core of explosive composition (e.g., flash powder or, less commonly, black powder) which is generally encapsulated inside two nested paper cups, typically of the type used to plug the ends of an M-80, which is in turn most commonly surrounded by a layer (approx. one-quarter inch thick) of sawdust infused with a ...
Roasting the turkey. It cooks at 350°F, slightly cooler than the Test Kitchen's preferred temp of 375°F. At this point, I was confused by Butterball's directions for how long to cook the turkey ...
The velocity of detonation is an important indicator for overall energy and power of detonation, and in particular for the brisance or shattering effect of an explosive which is due to the detonation pressure. The pressure can be calculated using Chapman-Jouguet theory from the velocity and density.
