    Awesome prank! I probably wouldn’t try this one, but I’d love to see it done in someone else’s kitchen!

    @bea, um, yes they do. I know right before i open a bottle of ketchup there is that watery liquid that sits on the top of the ketchup, so I shake the bottle two or three shakes. Just a habit now. However, after seeing this I will be more cautious now. LOVE THIS!

    And what stops the vinegar from reacting with the baking soda immediately.

      It doesnt foam right away cause its a small surface area of the baking soda on the ketchup, so only a little will react with the vinegar to start with. It says to be careful not to shake for that reason. Then when they shake and it mixes in more baking soda mixes with the ketchup and the pressure increases and it pops. You probably wouldnt want to leave it for more than a few minutes before they open it though.

    I think people dont shake ketchup bottles. Maybe they would shake it a little but it wont be enough to trigger an explosion that huge.

      I dunno man, someone could get me so good with this. As I always shake the shit out of the ketchup bottle before I use it.

    Hey, Prankked here, I love all the talk about it, but I think it might clear up a few questions, if you tried this one yourselves. Like @fajas, on how many shakes does it take to get an explosion of that magnitude. (by the way, for this graphic, I shook that ketchup bottle up and down 4 times when it began to expand the bottle so much I put the bottle down and quickly walked away. Haha, when it blew it’s top.) Or @andrea, what keeps the baking soda from reacting right away, as long as you don’t mix, or shake the bottle, it will be just fine, which is why it’s important to just let the ketchup from the sides cover the baking soda. However, I would HIGHLY recommend performing this one outside. It’s a lot more powerful than I had thought it would be. Took me over 3 hours to clean the kitchen and part of the dinning room after it went off.

    Have fun!!

    Yuck! I hope my kids don’t see this website. and if they do, I hope they don’t mind cleaning ketchup off every surface in the kitchen.

    Bea – have you never heard that old rhyme, “Shake and shake the ketchup bottle, nothing comes and then a lottle?”

    so what happens if they have the new no spill lids that’s going to be a lot more pressure build up wouldn’t it.

      This is an extremly valid point,but if u look closley at the last pic of the exploded bodle u notice that i has a very narrow spout,not much wider than a no spill lid, you could cut out the little things(no spill things)instide the spout to give it the same potential preasure shown in the last pic.

    Are you kidding me?? This prank is golden. I can’t count the times guys go for the ketchup, give it a few hard shakes (without paying attention mind you)and pour it as fast as they can so they can cram down their dogs..

    Anyone who says other wise lives under a f**king rock.

    I had this happen WITHOUT adding any baking soda. I had made homemade ketchup and put it in an old ketchup bottle. I got tired of it and forgot about it leaving it in the fridge. Months later, my buddies ran out of ketchup and a guest found a bottle in the back of the fridge. Of course he shook it up ( since it looked watery) and went to open it. several loud screams later and the ceiling looked like bloody ax murders had just happened. I can imagine that the my homemade mix fermented and made it’s own gas powered eruption and it reached the ceiling and the florescent kitchen lightbox. We didn’t have a ladder so it stayed there till we moved out. wonder if the landlady ever noticed?

    Wouldn’t try with a glass bottle though…

    Ha thats cool. You can do a similar one with diet coke and mentos. Pour out a little of the coke, tie a thread around the mints and put them into the bottle, with teh end of the thread sticking out. Put the lid back on and it will hold them in place, until someone opens the bottle

    It would foam out as soon as you put the baking soda in, the only prank would be on the person cleaning up after you run away screaming like a little girl.
