If you are a heavy "sleeper" and you always need an extra volume to wake you up. I would like to introduce you to this Bahbak Hashemi-Nezhad DIY project, the wine glass resonator. You just need to break the leg of the wine glass, put it lending down on the table and put in your mobile phone. Make sure you set the loudest volume and point it to the right direction. I’m sure that is quite alarming!
