Light Sensitive Sound Box

April Fool’s Day is still a good one month away, but now would be a good time for you to build up your arsenal of weapons as you attempt to out-annoy your colleagues and friends. This Light Sensitive Sound Box ought to do the job admirably, although chances are they will be easily traced by the victim within a few minutes. Available in different sounds, you can choose from a dripping tap or a barking dog to frustrate that pesky intern to no end. Place it in a box, drawer or just turn off the lights to see these nifty little sound boxes go to work. A great prank to play on the last guy to leave the office at night – he’ll probably wonder where the dripping tap sound is coming from.
