The problem with most alarms even traditional alarm clocks is that the noise exits the speaker and radiates outward in every direction. Well Bahbak Hashemi-Nezhad came up with this ingenious little device to focus the alarm sound in a single direction. The invention isn't any simpler than a deep red win glass with the stem broken off. Don't you just love 1-step DIY projects. The greatest part is that you don't even have to crack open a toolbox to get this to work.
So dust off the wine glasses that haven't been used in oh so long - because bachelors drink beer - and get some use out of them. I'd admit that you might run into a problem if you're one of those people who tends to smack their cell alarm to shut it up; but at least if the cell phone doesn't work, the shards of glass causing your hand to hemorrhage will do the trick.
