yo! gurt!

Who doesn't like yogurt? You? No? Not you? Your friend? You best friends moms uncle's cousin's wife's brother? Ya him? Okay cool. But since you do like yogurt let me tell you the chemistry behind it. It is all made from some old milk and bacteria. Sounds delicious right? But u said you liked it...so..... The milk is fermented by bacteria. The lactose in the milk, C12H22O11, changes to lactic acid C3H6O3. This makes the milk thicker and it lowers the pH level. The acidity of the fermentation gives the tanginess to the yogurt. Then from there you can add the flavoring like strawberry, bayberry, and stickberry! Do you see what I did there? Like straw, hay, and stick like the cows eat the.....whatever.......I know you really understood and you just did not want to admit it. :p
