One thing I've never understood about the conservation of energy is how it works with the concept of heat death.
With every physical process, some energy is wasted as heat, which eventually cools down (i.e., the molecules stop moving). Physics says that the energy that caused those molecules to move previously is "still there" somehow, but it can't be extracted.
If every bit of heat wasted from a system eventually becomes permanently useless, why doesn't that count as "destroyed"?
Because you can't destroy energy, meerly convert it. The heat energy is still heat energy, but it is dispersed over a wider area, thus it feels cooler.
very educative!!! now i feel smarter

i'd say it was a pretty rad demonstration, but warner music has disabled the audio on your video. :(

Those must be some mighty shockwaves.
