[3] There are two types of electric tube, one with long wires for joining up with the electric circuit and the other without external wires.
Moreover, when heating the tube with liquid or solid contained inside, the holder ought to tightly hold a test tube [5] in order for the tube to be safely held while heating. [ 6 ] Particularly, for liquid heating, when holding a test tube holder with a test tube, hold it such that it aligns with the lab bench and also point the open end of the ...

The first step to firing a firearm of any sort is igniting the propellant. The earliest firearms were hand cannons, which were simple closed tubes.There was a small aperture, the "touchhole", drilled in the closed end of the tube, leading to the main powder charge.
Detonating cord (also called detonation cord, detacord, detcord, blasting rope, or primer cord) is a thin, flexible plastic tube usually filled with pentaerythritol tetranitrate (PETN, pentrite). With the PETN exploding at a rate of approximately 6,400 m/s (21,000 ft/s), any common length of detonation cord appears to explode instantaneously.
