this prank is pretty simple, with very destructive and stressful results. it ends with the toilet overflowing with an emulsion of carbon dioxide bubbles.

  sorry for the slight lack of pictures. I don't have a legit camera, so I took most of them on my computer's webcam and one of them with my cell phone.

Step 1: ingredients

these ingredients are fairly simple. the only thing you could have a problem with is the citric acid, which you might be able to find on the internet. I found mine at an amish store.

citric acid

baking soda

dish soap

Nice. I can think of some fun things to do with this... <br><br>Citric acid is sometimes in baking or candy supply stores, and sometimes in health food stores. I always keep it on hand, for:<br><br>bath bombs<br>making invert sugar <br>all sorts of candy that needs a little tartness, like pink lemonade marshmallows<br>mixing with baking soda to make sodium citrate, to make a smooth nacho cheese sauce<br><br><br>I never thought of adding dish soap to the citric acid and baking soda. My kids would love playing with all that foam. Great instructable!
ha, I totally forgot about this instructable.<br><br>thanks for the input.
This is one of my childhoods harshest pranks! We managed the load size and flush timing, so that at our school the explosion came out one floor below the insertion place. We also made it with carbide from construction sites (also fun combining with water and fire), and some chemical for plants, which reacted with water. The most fun was keeping this secret to a small group of insiders. But the secret always came out with not so much fun afterwards. The version number one, long before this, was with the dry toilet (without water, just the stuff) and adding yeast to it. Much of it. It is slow, but what a mess!!! And nobody can stop it.
wow. that's a bit.... um.... more impressive.<br />
