i have seen special travel toothbrushes that do not require water or toothpaste to use properly, the brush is stored upside down in a small container filled with some liquid. wenn you use it you take out the brush and put in upside down on the container, so you will end up using it as handle. they come in diffrent colors 2, if i rememeber correctly <img src="images/graemlins/cool.gif" alt="" /> what else can you ask from a toothbrush ?

btw the liquid stuff is only enough for 10 brushes....
