Stripy Toothpaste like AquaFresh

I'm sorry, i've been sitting playing with my aquafresh tube for ages now, and i can not work out how it comes out stripy.

Any ideas?

It's stripy within the tube? :S

Then it wouldn't come out stripy, it would mix.

My one iv got atm is meant to be white and green but its all mixed, idk how :S

I think the different colours are slightly more viscose (thicker paste) than the white stuff therefore it stays in position.

Just a guess.

the nozzle thing has a gizmo in it that separates the different colours :)

So far found out that the different colours do absolutely nothing different. they are just coloured. So if its like 3 in 1, its actually 1 in 1 with 3 different colours

The reason for the stripes:

In each tube of toothpaste there's a little bit of zebra fat at the bottom to make it all stripey ;)

Im telling you, Thats all lies, Its all about the zebra fat..
