Answer :
he Sprite and Banana Challenge consists of eating two bananas and then drinking a liter of Sprite. This causes you to projectile vomit and throw up all over the place!
The experiment with eating two bananas and then drinking a Sprite has not shown any chemical reaction by people who have done the experiment. People who have studied this believe that it makes some people vomit simply because it is a lot of food to put in your stomach at one time. Most people do not vomit, rather they tend to feel sick after.... i know this because ive done the challenge xD
