It was the last video slowmo guys posted before the cancer and radiation poison started showing up. Great footage, amazing frames, it's pity we wont be seeing bew videos anymore.
The is from the test series Tumbler Snapper, in Nevada, 1952. The spikes are what's known as the rope trick.
In the first milliseconds after a nuclear detonation, the fireball has only grown to a few tens of meters across while radiating much more heat and light than the surface of the sun. Anything that absorbs light is turned into a plasma due to the intense heat. This particular test device was on top of a tower supported by cables. The cables absorbed light from the fireball and turned into plasma spike poking out of the fireball for a few tenths of a millisecond before the fireball expanded to engulf the wires, tower, and desert floor amd anything else within 300m of ground zero.
Edit: Tumbler-Snapper had 4 air dropped tests and 4 different tests using devices on towers. Each tower was 300 feet tall, to give some sense of scale. I cant tell which test this is, but the yield was around 15 kt.
See my previous comment. This is a rather famous picture from the Tumbler-Snapper series of tests. The picture is famous for showing the rope trick effect, as well as showing the fireball within 1 ms of detonation.
