Experiment Demonstrates The Crazy Effect Milk Has On Coke

Always Coca-Cola? Not if there's milk involved.

Mixing Coca-Cola with milk probably never was on the top of your to-do list. But we wouldn't be surprised if after watching this video you were to feel enticed to set up an impromptu chemistry class in your kitchen.

YouTuber Maricv 84, who is already famous for his Coca-Cola vs. Coke Zero video, has done yet another experiment with America's most beloved soft drink. 

This time, Maricv 84 uses milk to demonstrate the crazy chemical reaction between the phosphoric acid and the calcium contained in milk. The results are simply astonishing.


For his experiment, Maricv 84 takes a little bit of milk and pours it into a bottle of regular Coke. He gently shakes the bottle and lets it sit for a while.

After about 15 minutes, the craziness starts to unfold.

20 minutes in and the previously black liquid starts turning ... clear?

The strange chemical reaction happens when molecules of the phosphoric acid contained in Coca-Cola bind to the milk molecules, giving them more density. The milk starts curdling and turns into a dense, solid compound that sinks to the bottom of the bottle. The molecules that weren't affected by the phosphoric acid remain light and float on top.

According to Maricv 84, some studies suggest that the high levels of phosphoric acid found in most soft drinks increase the chances of developing osteoporosis in people who don't get enough calcium. 

However, the National Osteoporosis Foundation claims "there is no scientific agreement about whether the current level of phosphorus in the American diet is harmful to the bones." 

Watch this video to see the fascinating experiment for yourself.
