Can anyone give a scientific explanation on this please?

Density

aren't you to young to see such a video?

 

indeed density, alcohol is lighter then water and when hardly disturbed will float above it, the colouring part of whiskey has an affinity for alcohol above water so it follows it to the surface of the liquid.

 

Note that when you shake the glasses to hard, it won't happen, alcohol and water mix very good (hence not the whole color went to the top)

thanks

you couldn't for example do this wit beer, you need something with a high alcohol amount to have a noticable effect.

Damn... Betsy beat me to it!

I beleive this is also the principle behind "floats" where people manage to get alcohol to lie ontop of other liquids to get multi-color drinks. Bloody hard to do though-my gf can but I am hopeless. 

you need to pour it in from the side icewolf, least disturbes the boundrylayer

Its much harder when you use Port, a napkin and water

Take a spoon, flip it upside down then touch it to the glass above but near the last layer. Pour your next layer over the back of the spoon. Might need to replace/wash the spoon for each layer. 

 

Easy peasy

I've tried it. Didn't end well for my new jeans.

 

Also, this is older than balls, Sammy. Go back to drinking from a sippy cup you're too young anyway!
