    That recompression luminescence is suggestive of what happens in extreme cavitation. V odd.

    Very nice videos, guys. But I'd like to challenge you.
    75 years ago, in the middle of WWII, some such experiments were done by the Navy. The video they made is at usclip.net/video/MPJjMJ48CdY/video.html. They found more story than yours did because they used bigger charges in a bigger pool. As it happens they discovered several phenomena beyond just the bubble - recoiling bubbles, and the affinity for that the bubbles had for close hard surfaces. I'd surely like to see you reproduce their results, not to tweak you, but rather to see their results at modern camera resolution and speed.
    As it turns out their research had application to various nuclear underwater explosions, most notably Crossroad/Baker. The vid you made of the surface effects has interesting parallels to the above-water views of Hardtack1/Umbrella (see, for example, usclip.net/video/aj1VFwUkUk0/video.html)

  • LastDays70AD Daniel12

    Of course it adds air to it, that's why it explodes. The black powder creates expanding gas. And that is exactly what you see, a sphere of gas. Very hot too. And notice the energy converging after maximum expansion as a bright light. That's pure energy. Without substance-matter, released initially by that ignition.

    Guys, if you shoot these things in front of a blue or green screen, then young film makers can use them! You could even charge them a nominal fee if you liked. Point is, creative people could benefit. Not to mention these effects look much better (and more organic) than some CGI contrivance. Think about it lads! :)

  • Guillermo Acevedo
    Guillermo Acevedo 17 days ago

    Did you notice the wave patterns on the sphere? I think they might be due to tiny droplets that get left behind as the wall of the sphere grows after the explosion, but still retain some kinetic energy, so they follow this "wall" and when it stops, they "fall" on to it from the inside. If you look closely, when the sphere starts to diminish in size, this pattern starts to increase in frequency, as the wall of the sphere collapses and moves to and into the little droplets that still remain inside. What do you think about it?

    Hey men its look amazing.!! Thanks to share it. Maybe you try whit different explosions a little bit bigger perhaps make more implosion and cavitation effect. its real beauty when bubble colapse and compress the inner gas and turn it too hot as its bright and shine.

    The Big Bang...the expansion and subsequent collapse of the universe. 13.7 billion years so far and the universe is still expanding...but excellent model of how it will eventually collapse back on itself. Great video, guys.

  • AlexCryptoTV

    the second explosion on compression is from cavitation.. you get the same effect when a high speed bullet enters ballistic gel and it compresses the cavity back. You can also see ignition even though there are no more volatiles in the projectile or the gel.. physics are awesome

    To what they talk on minute 5:40, i think that because the pressure of the water pushes that air buble, and the volume of that air sphere reduces, is that the temperature rises. And because of that you see the light even brighter when it's ending.

    What is depicted here is the physics of the big bang. In that the detonation, expansion, retraction are physically the same, the only difference is the massive expanse of time for the big bang to retract back to the beginning. The black hole part is when that bubble gets ducked/pushed back inwardly
    Another awesome video from the slow mo guys!
