We have a plastic cake dish that isn't used for much except containing, i.e. it doesn't need to look pretty. Recently it got a big ole crack in it, and I was charged with the job of fixing preventing any further damage.
Using some plastics glue I picked up for this project, and a toothpick, the cake dish is now all better.
Not warranting a full instructable, I smeared some glue in towards the edge of the crack, where i could fit it, and then covered the crack, on both sides, with a layer of glue to hold it together.
