At first 10min seemed like too long, but it managed to stay interesting the whole time. Simply amazing, I can't think of any other words for it. Everything looks like a liquid.

Ever heard of the Deborah Number ? The name comes frome the bible :

"The mountains flowed before the Lord" in a song by prophetess Deborah recorded in the Bible (Judges 5:5)

It's actually used in rheology to describe if a materials acts more like a liquid or a solid. Even mountains acts like liquid at a big enough time scale :)

Interesting fact: the light flickering is due to the current alterations in the light bulb.

I had seen this before too but I liked watching it again.

Interesting at first, but after a couple minutes of video without any kind of explanation of what the bullets were actually doing, this got boring quick.

With such visually compelling frames, why not throw a popover that provides some context for those of us without physics degrees?

Actually, what put me off was that they didn't even at least tell us what material it was striking.

This was really cool to watch. However, I wish there was information on the properties of each of the substances being bombarded with bullets. I could make reasonable guesses as to what some of them were, but does anyone know if this is available anywhere?

That was pretty cool, but I kept skipping forward 30 seconds, to see all of the effects without taking 10 minutes.

I really enjoy spending time at the shooting range (yeah, it is an Arizona thing :-), so the video gave me an interesting perspective.
