I'm sure you've tried mixing diet coke and mentos together, or at least know what happens. The reaction of the two mixing turns in to a huge explosion of soda! Sai couldn't wait to see what mixing the two together would look like inside of her stomach. Sai guzzles down diet coke and swallows an entire roll of mentos in this clip. By the end, her massive stomach is jumping and moving around as if she was pregnant!
