Bass Pro sells a box of the Gelling powder (called Bio-Gel) for 10 bucks. Use your own baggies and make simple Wagg bags. I used it tent camping this weekend. I used the twist top Glad containers from Wal-Mart, and set a plain plastic bag (bread storage kind without a zipper) inside, hanging over the edge. Put in a scoop of powder. Afterwards, I tied off the bag, and twisted the lid on the container to be triple sure it wouldn't leak in the middle of the night when I knocked it over. (FYI - I am female.)
