CrazyRussianHacker is known for his crazy science experiments. This time, he added Red Bull to milk and you see how the chemical reaction takes place. And he was smart enough to not to drink it like many people on YouTube did to make it a crazy challenge video to get views. This guy got about as many views as them, just without the “serious toilet problems,” as he calls it.
When you mix milk and red bull, the acidic properties of red bull cause the milk to curdle. Which means it separates into curds or lumps.
So it is a chemical reaction between the acid in the red bull and the casein in the milk which causes the fluffiness when the casein (a protein found in mammalian milk) separates from the milk due to the acid.
Turns out red bull has a lot of side effects on your body when mixed with other things such as alcohol. Do not drink red bull with alcohol, it can cause severe chest pains and heart attacks. Milk and red bull have a similar effect on your digestive system. You might definitely vomit or get intense diarrhea. So try this experiment if you want but don’t drink it.
