Red Bull and Milk Reaction



Did you know if you mix milk with Red Bull, the milk will curdle? Pour milk (whole milk works best) into a glass. Then, pour Red Bull on top. Let the solution sit for five minutes. The acid in the Red Bull causes the protein (casein) in the milk to separate. This is a great experiment to do with a states of matter unit. When the milk curdles, a chemical reaction takes place, resulting in a precipitate. 


Below, Mr. Mishler's second grade class tested Red Bull on five types of milk.

  1. Maybe it'll also be a lesson on why not to drink Red Bull!

  2. How much milk and how much red bull is being used?

  3. Hello! I am a ninth grade physical science (physics/chemistry) teacher. I see that there is an error in your content on this page. Phase changes and states of matter are physical properties/changes. Causing milk to curdle is a chemical reaction making a precipitate. They are not the same thing. While it is a common misconception, please correct that on this site. I love all of the ideas on your site, but I had to say something about the content here.

  4. Love this. Cool Visual with the Red Bull Can; Vinegar will do the same thing (typically about 5% Acetic Acid) at a much lower price and you'll have lots left over for other experiments.
