In a normal soap bubble, surfactants reduce the surface tension of the water and allow the bubble to form. To create a colored bubble, dye molecules must bond to the surfactants. Each dye molecule in Zubbles is a structure known as a lactone ring. When the ring is closed, the molecule absorbs all visible light except for the color of the bubble.
The M134 Minigun is an American 7.62×51mm NATO six-barrel rotary machine gun with a high rate of fire (2,000 to 6,000 rounds per minute). [2] It features a Gatling-style rotating barrel assembly with an external power source, normally an electric motor.

In a stationary, heavy machine gun role the MG5 can also be mounted on the MG3 Feldlafette buffered field tripod by using additional adapters. The Bundeswehr use a RAL 8000 green brown surface finish on their MG5s and has chosen to use a 550 mm (21.7 in) barrel instead of a 663 mm (26.1 in) barrel for their mounted guns to promote parts uniformity.
The Type 100 and Type 1 weapons offer the advantage of two guns being mounted in the space occupied by one gun of the same size, thus saving weight in the gun and mount, and space in the plane. A small ammunition supply making frequent magazine loading necessary was a disadvantage, partially because of the advantages of the double barrel principle.

In 2013, it hit a milestone by producing its 1 billionth soap bubble bottle. 2015 saw the installation of a new, more efficient automatized line for production and the establishment of a US ...
Lead bullet being supported by a wooden cup sabot in a Delvigne gun. A cup sabot supports the base and rear end of a projectile, and the cup material alone can provide both structural support and barrel obturation. When the sabot and projectile exit the muzzle of the gun, air pressure alone on the sabot forces the sabot to release the projectile.
