Curdle up! - Why does milk get sour? (Experiment) |
by Mya Kagan (whyzz writer) >> more about the author
You’ve just learned that when acid gets into milk, it causes the milk to become sour and turn “curdled.” There’s a very easy way that you can see this process for yourself!
All you’ll need is a small cup of milk and half of a lemon.
Squeeze the lemon into the milk and watch what happens. You’ll notice that milk almost immediately starts to curdle when the acid from the lemon gets mixed in!
Gross!!
