I’ve always wondered… how does Aquafresh toothpaste always come out with the 3 different ‘parts’ without them getting mixed up in the tube?

Oh, I saw this in a “how do they do that” book. From what I can remember, the main compartment is all the white toothpaste. Then, there’s a separate compartment that’s a ring around the opening, and that contains the colored stuff. Squeezing the tube forces the white stuff out through the hole in the middle, and the colored stuff through tiny holes surrounding the main one.

I did and the master speaks [here](http://www.straightdope.com/classics/a1_173.html) about Stripe toothpaste.

The Aquafresh [website](http://www.aquafresh.co.uk) has information too (click on “The three stripes toothpaste factory”) which looks basically the same.

Essentally the tube is filled up in the correct fashion and the special nozzle makes things come out in three layers.
