This is a video of Grant Thompson and that guy who flushed mercury down a toilet seeing what happens when you flush sodium down a toilet. SPOILER BUT NOT REALLY BECAUSE YOU ALREADY SAW THE SCREENSHOT: it explodes. So, if you ever wondered what comes out of your ass after eating suicide hot wings, I guess it's pure sodium.
Keep going for the video.
Thanks to Craig, who flushed a dead fish down the toilet with much sadder results.
