7.83HZ Schumann Wave Ultra-Low Frequency Pulse Generator & Audio Resonator, DC

I have read where these new age contraptions supposedly help everything from sleep to your love life and cause everything from anxiety to cancer so take your pick.

There ya go, like I said it's  a cure all or a curse depends on which tale of salvation or woe you encounter.  No telling what these children do when they escape the mind altering influence of the resonators. 

I wasn't  judging  the students. Let me know if you ever figure it out.
