automatic toothpaste: just add water

With NAB and a pending overnight flight to Las Vegas, I have to consider what I can bring in the carry-on.  Tubes of toothpaste appear to be limited to the tiny ones.

I'm going to head out to the drug store to see if these instant toothbrushes work.  Supposedly you just add water and the toothpaste springs to life in the bristles!  See the picture?  It's gotta be good.

Just in case, I'm gonna bring my regular Radius Toothbrush and a little FAA approved tube.  

I just hope that this experiment isn't as disastrous as the sea monkeys debacle.

Hmmm... that paste is about the size of a pea, right?
