Breaking glass with sinus tone.

In technology class we always try to push the limits and lately we've been trying to break a wine glass by analyzing it's resonant frequency and replay it with a sinus generator at very loud volume.
First of all it doesn't work with normal wine glasses, cristal is best and is easy to resonate by making your finger wet and rubbing it over the edge of the glass in circles (you know the old trick) we managed to vibrate the glass to a certain point but the breaking didn't occur....Probably not enough juice from the speaker next to it!
Anyway you can try this experiment at home it's pretty cool!

Here's footage from a university who did succeed and filmed it in highspeed!

Online funny music application

Casper, one of my 13 year old bassguitar students , showed me this cool link called hobnox audiotool.

Hobnox Audiotool is a cool little music app for online composing, it feautures all of the typical plugin bussiness like roland 808 and 303 emulations as well as a bunch of standard boss like fx. Not mega exciting I know but when bored and surfing it's a creative antidote.
