The conversation is between two individuals, Gav and Dan, who are testing the phenomenon of bullets skipping off the surface of water. They are using a smaller round (2-2) instead of a 50 caliber because the round is more appropriate for the size of the fish tank they are using.
They are using a Phantom TMX 7510 camera to capture the event at 82,000 frames per second with an exposure time of around six microseconds. They predict that the bullet will either miss and hit the glass at the back of the tank or it will go underwater a bit and then kick off and come out, hopefully not damaging the tank.
The first bullet they fire does indeed ricochet off the sand, which is part of their setup to protect the tank. The bullet leaves a visible trail in the water, and they measure the time it takes to hit the tank and how far it travels. They notice that the bullet travels only half the length of the tank before it starts to tumble.
They then try a red tip Tracer round, which is slightly larger and longer than the previous round. The Tracer round leaves a visible trail in the air, making it easier to see the bullet's path. The bullet doesn't break the glass but deforms it, showing that it hit with enough force to deform the bullet but not enough to break the glass.
They discuss the possibility of shooting a 9mm pistol round to see how it would affect the glass. They predict that it would cause more damage and possibly break the glass. However, they decide not to do this for safety reasons.
The conversation ends with them discussing their merchandise and their second channel, and they thank their viewers for watching.
Here are the key facts extracted from the text:
1. The experiment involved shooting bullets at a fish tank to see if they would bounce off the water.
2. The experimenters used a Phantom TMX 7510 camera to record the shots at 82,000 frames per second.
3. The first shot was with a 2-2 rifle, and the bullet skimmed the surface of the water and bounced off.
4. The experimenters also used red tip Tracer rounds, which have a pyrotechnic mixture that ignites when fired.
5. The Tracer rounds made it easier to see the bullet's path and allowed the experimenters to measure the speed of the bullet before and after it hit the water.
6. The experimenters shot a 9mm pistol round at the fish tank, and the bullet bounced off the glass without breaking it.
7. The 9mm round displaced more water than the 2-2 rifle shot, and the experimenters measured the displacement by inserting their arm into the tank.
8. The experimenters calculated that the 9mm round would have had to travel at a certain speed to slow down enough to bounce off the glass without breaking it.
9. The experimenters inspected the bullet after it bounced off the glass and found that it had deformed slightly.
10. The experimenters repeated the experiment with a different angle of incidence and found that the bullet still bounced off the glass.
11. The experimenters noted that the glass had withstood the impact of the bullet and that the tank was still intact.
12. The experimenters estimated that the 9mm round had used up 97% of the glass's "Integrity" (a term borrowed from Star Trek).
