The idea that Alka Seltzer and other gas-producing chemicals make seagulls burst is untrue. Seagulls can reject bad food sources before they cause any harm because they may vomit the contents of their stomachs.
According to the urban myth about seagulls and Alka Seltzer, the tablet’s foaming and gas production will eventually cause the bird’s stomach to explode. The myth’s proponents assert that because seagulls cannot pass gas, they cannot tolerate Alka Seltzer. Seagull biology, however, refutes this claim. In a similar vein, birds do not erupt when they consume raw rice.
