RICHMOND, Va. (WTVR) -- Another online video craze is gaining popularity, and it can be very bad for your health. It's called the cinnamon challenge and videos of the act are popping up on online video sites.
To complete the challenge, people have to swallow a spoonful of cinnamon without any water.
When the cinnamon hits your tongue, it acts like a sponge and sucks up all the moisture in your mouth.
US poison centers said the challenge can make you choke, give you trouble breathing, and even collapse a lung.
