How Videos Are Faked On You Tube, (Excellent Job !)

Exactly......density/consistency of material.........the above was my FQ version (long-winded   ) way of agreeing with what you posted on Fackler.
I used to read a lot of articles by him and Ed Sanow.

That's the other guy !  THANK YOU PegLeg    

Found what was tickling my brain

Solus is correct, as are Peg and Tom.

Air is a fluid just as H2O and oil.  It's displaced by the energy of the projectile but doubtful with enough energy to cause any serious harm unless at super extreme conditions such as the expansion of super heated gases from a monster explosion.  At that point, the percussion of air can and will do serious physical damage.

A 50 caliber round passing by your head may puncture an ear drum but not much more.  It's merely displacing a wave of air at an ever decreasing frequency due in part by the density of the medium that it's traveling in...

The reason we could listen to submarines from 2000 miles away was because of the medium that the sound was traveling within:  sea water at a specific depth and with a specific temperature and salinity!

Physics is cool but it ain't rocket science!

Would that be a function of the Mass or relative lack there of ?

But Rocket science is physics

Let me try.....

Speed of sound in air is about 1168 feet/second or 768 mph.

Speed of sound in water is about 1500 METERS/second.

The more dense the medium, the more displacement of the medium when disrupted.  The reason the water bottle or watermelon explodes violently is more a product of the CONTAINMENT rather than the medium!

Bullets have a very crumby ballistic movement through water.  The higher the velocity of the projectile, the less damage it produces.

[tombogan03884]

So what you are saying is the shock waves travels through the water like a car on the highway until it comes in contact with the Plastic of the jug, or the rind of the watermelon which acts like a bridge abutment would on the car.
Result, sh!t flies every where in both cases

On the nose Tom....

Energy, if unrestricted, would travel forever in a vacuum.  Only the contact with another object or opposite energy would cause it to change or slow. 

As someone has already said, Newtons third law.....

YES!
Thank you Tim, that was what I was stumble-fingering around in my previous statements trying to get to, the containment or container is more directly involved with the 'violence of the explosion than the media, even though the media is also a contributing factor.

This thread definitely has me thinking about doing some testing.
No .50 cal, but a 30-06 with 180gr soft points might get me going. Maybe put a melon on a piece of pvc pipe with an egg underneath and shoot the melon to see what happens to the egg.

Shoot a full paint can with the lid off.  We will see just how much reaction the media has without complete containment.  Maybe anchor the can to the "board" so the can doesn't get tossed.

Shoot half a watermelon, both parallel with the cut and perpendicular to it.

Yeah, good idea....paint cans are cheap at Lowes.

I'm looking at getting one of those cheap $40 digital video cameras in the near future so I might wait and record the results and post them. I have a digital video recorder on my regular camera, but it is an older model and doesn't have sound.......and ya gotta have sound.

Some time back, Mythbusters was doing a "Shooting fish in a barrel" episode.  Regardless of what they were trying to prove, they had set a wooden staved barrel filled with water and Jamie was shooting straight down into the barrel with a 9mm handgun.

When he shot into the barrel, the slo-mo camera showed the water erupting up out of the barrel, the barrel jumping off of the floor and I think you could see the circumferential expansion of the barrel against the stave and rings of the barrel.

on a side note.....not once did the 9mm round penetrate the bottom of the barrel nor would I expect it too.
