Whiskey Floats on Water

This YouTube video demonstrates a physics trick right out of high-school science -- how to take a glass of water and a glass of whiskey and swap their contents, without using a third glass. It relies on the principle that whiskey is lighter than water and will float on top of it. The funny part is not the video, which is fairly straightforward, but rather the comments left by YouTube viewers, many of whom seem to think the video must have been faked. I guess they weren't paying attention in high-school science. I had a bottle of cheap whiskey on hand (Rebel Yell), so I tried the experiment myself, and I can attest that it definitely works. You just have to make sure not to allow the whiskey and water to mix too quickly, otherwise they'll combine together and you'll end up with two glasses of watered-down whiskey.

I saw this in a Paul Zenon book, but I've never tried it. I always wondered what it'd look like. I'm going to try it now and see it for myself.

I love how the Youtubers don't understand the science behind it. And are so confident in their convictions too.

Come on man! Rebel Yell is like the Buick of whiskey. All the quality without all the price!!

Is there any other substance that I could do this with besides , seeing as how I'm under the age to drink and none of my family drinks . Like, would vegetable oil work?

I think vegetable oil should work. In fact, it would probably be easier to do it with vegetable oil, seeing as oil and water mix far less easily than water and whiskey.

You should also be able to do it with a glass of freshwater with a drop of food coloring in it and glass of saltwater without. The saltwater is denser and should go on top.

But obviously this experiment _must_ be a fake. Remember, YouTube is the voice of the people, and the voice of the people is always right 😊

Or does it show something else?

I'd like to do it with a glass of freshwater with a drop of food colouring in it. I'll try it at home
