Singing Wine glasses
= = =Question= When you make a wine glass sing would putting more water in the glass make the note deeper or would it make it higher? = = =**Introduction**= I wanted to do my project on something with music and pitch. I had a list of ideas, and finally I decided that Testing the notes of wine glasses would be awesome to test!

=Hypothesis= I think that the more water the higher the pitch because, when you add water in the glass it, makes the molecules vibrate more to make the pitch higher.

= = = = =Background Research= The water changes the pitch of the singing wine glass because, the deep clear waves move around in the glass. It drags the water molecules with it, creating a wave of water that you can see near the side of the glass. The dragging water molecules increase the mass (both the water and the glass molecules) and make smaller energy of the wave going through the glass. When the energy is smaller so is the frequency of the wave in the glass, which is reflected in the pitch of the sound wave that you hear. = = =Procedure= Get four wine glasses and label them 1-4. Then fill them each up with different amounts of water. Fill wine glass 1 up with 1/2 cup of water. Fill wine glass 2 with 6 tsb. of water, glass 3 with 4 tsb. of water, and glass 4 with 1 1/2 tsb. Fill a cup up with 30 tsb of vinegar. Dip your finger in the vinegar and rub around the top of the wine glass with the tip of your finger lightly and rapidly. It might take a minute but then you will hear a small sound.

= = =**Questions for further study**= Would it matter the quality of the wine glass? Can you make glasses sing still without putting vinegar on your finger? If I added different liquids would it make a difference?
