Depending on how well youâve kept up with fire extinguisher maintenance, your portable fire extinguisher should last, essentially, forever. If youâve had the same fire extinguisher for a long time (10-12 years),one way to test its condition ) is to have it hydrostatically tested. A hydrostatic test exposes your fire extinguisher to high pressure (usually 500psi) to check the integrity of the shell.
Jingle Bells was the first song broadcast from space, in a Christmas-themed prank by Gemini 6 astronauts Tom Stafford and Wally Schirra. While in space on December 16, 1965, they sent this report to Mission Control : Gemini VII, this is Gemini VI.
Origin [edit]. The song gives a fabulist account of a ban on rock music by the king being defied by the population, who proceed to rock the casbah .. The king orders jet fighters to bomb any people in violation of the ban. The pilots ignored the orders, and instead played rock music on their cockpit radios.It was inspired by the ban on Western music in Iran after the 1979 Islamic Revolution.he king orders jet fighters to bomb any people in violation of the ban.
