Disposable Camping Toothpaste

When I go backpacking and don't have one of those tiny travel tubes of toothpaste, I'll make my own so I don't have to cart the large tube of toothpaste with me. I simply take a piece of Aluminum Foil and fold it so it's doubled then squirt a line of toothpaste on it, then I fold the aluminum foil up and seal the edges by folding and pinching them, then I fold over each end several times then put this in a zip-loc baggie.

When I want to brush my teeth, I just unfold one end and press on the bottom.
