Turn a broken wineglass into a cheap phone alarm amplifier

This is a great idea: to boost the volume of your phone's alarm — say, if you're a heavy sleeper — you can rest it inside a large wine-balloon that's had its stem snapped off. The glass bowl acts as a resonating chamber for the alarm. Some enterprising glassblower should do a purpose-built version with an integrated charger.
