*4 or more different sized wine glasses. Make sure they have a neck on the bottom.

* A bottle cap full of water

What to do:

1) Line up the four or more wine glasses in order from largest to smallest.

2) Wet your finger in the bottlecap full of water

3) Pick the glass you want to play first. The larger the glass, the lower pitch the sound you will make.

4) Rub your wet finger on the rim of the glass, rotating first slowly, then speed up. A high pitched sound should be heard.

5) Keep rubbing the rim of the glass. If you want to change the pitch, stop.

6) Wet your finger again, and repeat steps 4 and 5 on the new glass.

Now you can compose music very much like the music composed on the armonica!
