Prank a buddy with exploding ketchup!

Middle school lunch tables are begging for this prank. Wait, who are we kidding? Everybody's lunch table could use a ketchup explosion every once in a while!

This prank is from an enthusiastic kid who goes by the moniker SoccerBallz. Utilizing the power of baking soda, he pressurizes a bottle of ketchup to erupt on an unwitting diner.

Simple. Devastating. Brilliant!
