"There are more things in heaven and earth, than are dreamt of in your philosophy".

if you think thats cool you should see what my woman can do when you play metallica at her

not a fan of metallica huh:D?
or is she?
and what about you ? lol

That was pretty cool.

but on a side not im not sure what he said about ultra sound was accurate.

Since sound is the vibration moving through the air it will have to have some impact, and it's mechanical impact can be seen in its use in technology:

Ultrasoundings for medical use.
Ultrasound massage
cleaning used in denistry and industry.

there a fair amount of uses for it.

but on the whole a very nice demonstration
