How to amplify your cell phone with a wine glass

Recently I attempted to use my cell phone as an alarm, but ended up oversleeping because I couldn’t hear it.

However, there’s a quick and easy fix for this. All you need is a wineglass with the stem snapped off and the glass will amplify your cell phone alarm (think of your most annoying ringtone EXTREMELY LOUD). You’ll be sure to hear that alarm now.
