in the film Die Another Day bond is equipped with a ring that when twisted releases a high frequncy noise that can shatter glass. i want to be able to do this so can someone tell me the frequncy in which flat glass can be shattered or tell me where i can commercialy buy (online is fine) glass shattering equipment which is small and works in the same way.
why i want it:
school... no just for personal use.
