- Unexplained bright flash of light inside house - Physics Forums
From the video, the initial flash was very short, showing up at full brightness only for two frames (although it was preceded by a couple of frames showing a partial flash) Frames seem to be 30 per second, so that makes the flash duration between a 30th and a 10th of a second (You can use comma and period on the keyboard to step back or forward)

However, if you Google something like "Effect of Additives on the Flash Point of Flammable Liquid" you will find that you can begin by adding water to the alcohol to raise its flash point (for example, a mixture of 7 water 3 methanol seems to raise the flash point by 25 degrees C) You would then add this mixture to the petroleum
- Jet Fuel, JP-5, JP-8 DFM: Properties, Chemical Composition . . .
They contain hundreds of hydrocarbons as well as many additives The actual composition of any given fuel varies depending upon source of the crude oil, refinery processes, and product specifications The hydrocarbons in jet and diesel fuels are less volatile than those in gasoline JP-5 is a high-flash-point jet fuel developed by the Navy

Even comparatively dim flashes could appear bright when your eyes are in that situation Even though the flash itself might only last a tiny fraction of a second, the image sensed by your retina (which can include the walls floor ceiling -- anything lit by the flash) might last at least a little longer than that, just due to the way the eyes work
- Strange white flash in dark room. - Physics Forums
Yep Been there, done that Mine is a flash of a blue splotch about 40 degrees across my center of vision and with a handful of whitish speckles It lasts maybe 80ms It happens when I'm resting in a dark room with my eyes shut--usually when I'm half asleep,and there is a sudden noise

- Debunking the Myth: Do LED Lights Flicker? Get the . . . - Physics Forums
Many LED bulbs produce flicker - a rapid switching between on and off states Because the flickering happens at a very fast rate - typically 120 times per second or faster - it is not immediately observable to humans and appears to us as a light bulb of steady and constant brightness
- Removing the flash hider from the C93 (HK93 clone)
So, just got around to doing this article and felt the need to post it here It's on how to remove the flash hider from the muzzle of Century Arms' C93 rifle, although it should work for most HK-9x pattern rifles Before: After:
