A ringtone that only a kid could love... or even hear
Only dogs, not people, can hear a dog whistle. Something to do with the frequency of the sound. Well, it turns out that there are sounds that only kids can hear. In the past, that difference was exploited by malls in order to chase away youngsters by emitting the noise.

But credit one to the creativity of kids looking for a way to get around the constraints of a classroom. The Register reports that "British kids were quick to sample the sound and turn it into a ringtone to be used in class - they can hear it, but teachers can't." Furthermore, they did a quick test in the Register towers, and have confirmed that only adults can hear the ringtone.

So if you are a teacher and everyone in class suddenly pulls out their cell phones, now you know why!
