    I bought a jump rope, thought it would be better than running and losing weight. I was scared of falling, couldn't even make a jump. I am so unfit. Has it occurred to anyone here, that you cannot see your, well, ..., when you shower. This is terrible.

    "This film was produced in 1969 by Oak Ridge National Laboratory for the United States Atomic Energy Commission to inform the public regarding the history, technology, and milestones of the Molten Salt Reactor Experiment (MSRE). Oak Ridge National Laboratory's Molten Salt Reactor Experiment was designed to assess the viability of liquid fuel reactor technologies for use in commercial power generation. It operated from January 1965 through December 1969, logging more than 13,000 hours at full power during its four-year run. The MSRE was designated a nuclear historic landmark in 1994."

    Beirut, a few hours back



    That is some explosion.

    Mushroom cloud and all



    Small explosions building up to a massive one. Or just a second bigger one going off.

    Knocked the guy doing the video off his feet from over a km away.

    Lebanese security services have said the blast was caused by a fire in a depot of highly explosive material, including Sodium nitrate.

    They said that material was confiscated from a ship months ago and stored there.

    Lebanese security and medical sources have confirmed at least ten dead bodies have been removed from the scene of the explosion.

    The primary one maybe. The full-on second blast that took out half the city was probably the grain silo though.

    Destroyed grain silos amid the rubble and debris left by a massive explosion in the seaport of Beirut

    Explosion at Port of Beirut damages grain silos, terminal: reports | S&P Global | Aug 04 2020

    A depot at the Port of Beirut in Lebanon caught fire and led to an explosion Aug. 4, damaging the city's largest grain elevator nearby and causing material damage to other structures in the area, according to local media reports.

    Beside the grain silos, a grain terminal was seen damaged in the explosion, according to various reports and analysts. The port handles 60% of all Lebanon imports.

    The silos have a total capacity of 120,000 mt of grains, according to Elena Neroba, a market analyst at Maxigrain. The silos consist of 48 big cells, with a capacity of 2,500 mt/cell, and 50 small cells that can hold 500 mt each, Neroba said.

    The silos serve as a strategic storage for Lebanon, with about 85% of the country's cereals stored in the facility, according to trading company Mena Commodities.

    2,700 tons of ammonium nitrate

    https://twitter.com/BazziNYU/status/1290752400316301314

    In comparison the Oklahoma city bombing back in 1995 used 2 tons of the stuff

    Closest we get to this is the port of Texas city explosion back in 1947, where 2,200 tons of ammonium nitrate on a ship went off.

    The orange flames after the second blast are the fertiliser going off. Not the grain silos which acted as a barrier to the blast, with a good portion of it going seaward.

    So what caused the fire leading to the first explosion then ? the white flames.

    Fireworks (!) due to heat & humidity.

    You see how it develops here

    Fun fact. Ammonium Nitrate does not explode on its own when lit with fire



    So if there was 2,700 tons of it in a warehouse then a fireworks fire next door would not be enough to get the explosion we saw.
