"A long thin plastic strip, about 60cm long. It doesn't look like much,
but it talks! Along the length of the strip is a pattern of fine ridges
or lines. Run your thumb nail along the ridges, and the tape speaks.
However the sound needs to be magnified, so that you can hear it. One
method is to hold one end of the strip between your teeth. Then, when
you run your nail along the strip you hear it talk, but no-one else
does. Or you can stick one end of the strip to an inflated balloon or a
paper cup using sticky tape. The balloon or cup acts as an amplifier,
and you can then demonstrate it to anyone nearby. Never heard a balloon
talk? You have now!"
Plenty of other fun stuff on the site:

I remember these...about 15 years ago...going into a shop in silicon
valley buying a couple of these...they sang "happy birthday to you".
Ah...the memories!
thanks
