Title: 3 striped toothpaste
Post by: paul.fr on 19/04/2007 03:22:13

A leading brand of toothpaste has 3 stripes all the way through to the last squeeze. But how does the stripes come out seperately?

Ok then. Other brands of toothpaste only have a white stripe. How do they remove the other two?

Ermm.. I think I might know the answer, although it is a guess.

I think inside the toothpaste, if you cut it up, there are 3 tubes within the whole tube. The tubes are separated, probably in some sort of bag or something, and if you squeeze it, they come out separately and meet just at the top, where the three bags are joined together. This way, the colours do not mix, until right at the end, where it will not really collide alot.

Just a little guess of mine. [;)]
