What Happens When You Poured Milk Into Coke? I’m Totally SPEECHLESS.

Milk and Coca-Cola are the two most common things which you can find in most of the fridges. Both of these ingredients can be used in a variety of recipes.

From elaborate cake to simple bowls of cereal, milk helps make some delicious treats. Likewise Coca-Cola company lists dozens of ways you can use Coke in your cooking. But have you ever think of mixing Coke and milk together?

Sure, it sounds weird as one would think what’s the point. You probably haven’t, and when you see what happens, you’re probably not going to want to ingest.

Read on to see what happens when you poured milk into coke.

To start, just get yourself some milk. Don’t worry about it being “organic” — you’re not going to be drinking the stuff. Two percent milk will be the most effective.


Next, grab a resealable bottle of Coca-Cola. This won’t work with a can or pop-off bottle top. Don’t worry about splurging on the big two-liter bottles either. No need to waste perfectly good Coke!


Now you’re ready to go. Feel free to drink a couple sips of Coke to make room for the milk.

Go ahead and pour some of the milk into the bottle, but not so much that it reaches the lid.

While the bottle fizzes and the Coke begins to change, go ahead and screw the lid back on as tight as possible. Make sure that it’s airtight!

Seconds later after you poured milk into coke

Now you’re going to have to wait three hours. Why not enjoy a a soft drink while you do? Maybe a rum and coke? But once that six hours is over…


You’ll see that the Coca Cola has turned completely clear and the milk is now just residue at the bottom of the bottle.

Result... Whhhatt?

That’s really cool, but how does it do that?

That's really cool

Easy: The phosphoric acid and calcium react to precipitate 3Ca + 2H3PO4 /// Ca3(PO4)2 + 3H2.


Just kidding. I have no idea what that means either.

Basically, the phosphoric acid molecules attach to milk molecules, particularly the calcium. They grow in density and sink to the bottom. The remaining liquid is much lighter and floats at the top.

That solid stuff at the bottom of the bottle is milk that’s been curdled by the extra acidity of the soft drink.

Of course, that’s not the only way you can use Coca-Cola to create experiments.

One man drank ten cokes a day for a month to see what happened…and the results?

Not surprisingly, he gained over 20 pounds, and his blood sugar levels were much higher.

A mother dropped her child’s tooth in a glass of Coke for one month. By day 41, the tooth was so brittle it could be pierced with a needle!
