I know that works on sea gulls.
Have you actually seen it?

4. Exploding gulls.
Another exploding bird myth. I wonder why we are so attached to myths where something blows up. Must be the drama.
This myth proposes that if you feed a gull an Alka Seltzer tablet it will swallow the offering and when the lethal charge gets into the stomach and dissolves, the expanding gasses will cause the bird to explode. Every year there is another story about some mean kids doing this. Oddly, it always involves New Jersey.
After you stop giggling at the image of gulls exploding like flying land mines all over the Jersey shore, the unlikelihood of the myth starts to intrude. If it were true, it would be a big story. I can see the coverage now: Dan Rather in his safari jacket, standing on the windswept coast, hair blowing in the wind, gull feathers raining down in the background; PBS specials (who can resist the vision of a gull, cheerfully flying along and then suddenly exploding, right in front of the camera?); exposés in the tabloids.
If the body could not handle a little Alka Seltzer without an explosion, it wouldn't be legal to sell the stuff over the counter. If it caused gulls to explode, there would be a rash of reports every year. I do not know the physiological process by which the body processes a tablet swallowed whole (and I have no interest in trying), but I assume it involves, among other things, a fair amount of belching and a slightly gassy feeling. Actually, if I ate some of the stuff that gulls do, I would be thrilled to have a little relief, but they seem to do fine without it.
