Aquafresh! how?!

[Vonhelmet]

The next burning question is: what colour does the paste mix to when the red, white and blue are blended together? The Italian Job?!

You were only supposed to brush the bloody plaque off!

Wow, it's all from three different parts of the tube. Never would have guessed that.

Nicely solved OcUK.

Hahaha!

if one spent their life trying to work this out, it would not be a life wasted. think of the girls you would pull by using it as an opener? ''hey, do you want to know how aquafresh toothpaste comes out of the tube stripey?'' you'd have your hands down their pants within 22 minutes.

I managed it in 21 .

Can't say I've ever bought striped toothpaste, though, so I don't think I've ever thought about it. Interesting links tho

Can you believe in secondary school I had a whole Design and Tech project on this very subject that lasted a whole term (felt like years).

We even went on a trip to somewhere... where we discussed how it was made and the process which was used.

You know what?

I can't remember a flipping thing about it at all. Purely because it was the most boring project known to man. It probably could have been fun, but the way it was presented was dire.

It is this reason alone that I don't buy Aquafresh, mentally scarred for life.

Seen the mould for inside one of these things and it is RIDICULOUSLY complex

Ok well my girlfriend just turned around to me and asked how when you squeeze a tube of aquafresh it always comes out in stripes.... now we've looked on Google and even cut open a tube itself.... it seems for the most part that it is just put in in stripes...

Saying that if that is the case how does it manage to come out a smaller diameter hole than the tube's diameter and maintain this stripe pattern... I feel there must be an underlying engineering explanation!

What's more, surely if you squeeze one side more than the other it should mess up the pattern... but that doesn't seem to either...

I know I should probably be doing better things with my life, but now I have this puzzle stuck in my head I have to work it out....

Thought it might create some interesting discussion as well

It's funny you posted this question because it was explained in this documentary I watched just the other day: http://www.bbc.co.uk/iplayer/episode/b012ymht/Wonderstuff_Episode_1/

Girl in school wrote to them about this.

There's a separator inside the tube?

This might get you in the right knowledge set

This has been on Mythbusters (or a similar programme) before iirc.

It was on How it's made a few weeks ago!
