Hi

 

Would it be possible to separate two different flavoured smoothies in one glass so the colours alternate eg apple on the bottom, then blueberry, then apple again, sort of line a rainbow effect in a glass. If so how?

 

Thanks

Should be trivial for higher-viscosity fluids. If you add them without much flow energy, e.g. with a spoon rather than pouring, they shouldn't mix very much.

 

Google agrees, searching on smoothie layer or smoothie layered

thanks, would there be a way to make them so that if you shake it in a bottle the layers would go back to being layers and not mix together? Could you make alternate layers denser to prevent the layers mixing together?

"would there be a way to make them so that if you shake it in a bottle the layers would go back to being layers and not mix together?"

No, not with stuff you can drink.

You could get a layer of water and a layer of oil, but anything else you add will will mix with the oil or the water.

You need to start looking at rather more obscure things to get more than 2 layers.

A cocktail of mercury, perfluorokerosene, salt water, acetonitrile and dodecane will settle out into 5 layers after shaking, but you really wouldn't want to drink it

Perhaps he would have better luck with organic produce? As I understand it a lot of processed foods come with stabilizers and emulsifiers which prevent seperation. I don't know exactly what you're putting in your smoothies but it's an idea.
