>5. Seagulls will explode if they eat Alka-Seltzer

>There’s a long-held belief that if you feed a seagull an indigestion tablet, they will violently explode in a ball of feathers. The alleged science behind this theory is that seagulls are unable to pass wind, and the indigestion remedy therefore causes a volatile build-up of gases in the seagull’s stomach.

>However, there’s a major flaw in this pseudo-science. A bird’s diet may not require them to pass wind, but this doesn’t mean they aren’t equipped to do so. Also, gulls are experts at regurgitating their food, and could easily evict an Alka-Seltzer from the stomach if they found themselves in discomfort.

>Consider this myth well and truly busted.

But has anybody actually fed them one, especially when it starts fizzying up inside of their stomachs?
