Welcome to the mad-scientist wing of How To Revenge. This is our master guide to making fake everything — the DIY recipes behind the best harmless pranks, movie-grade special effects, and gross-out gags you can whip up with stuff from the kitchen. Every recipe here is cheap, most are edible or washable, and all of them are a lot more fun to make than to explain to a confused roommate afterward. Bookmark this page; it’s the hub for every “how to make fake ___” project on the site.
The Gross-Out Classics
Start here if your goal is a horrified double-take. These are the most-requested, most-searched fake substances we make, and they’re the backbone of our DIY collection.
- How To Make Fake Blood (Edible Too!) — our flagship recipe. Movie-quality, pourable, and safe to taste. Bright red for fresh wounds, darker for old. The one you’ll come back to every Halloween.
- How To Make Fake Snot — stretchy, drippy, and disturbingly convincing. Pairs beautifully with a fake sneeze and a well-timed handshake.
- How To Make Edible Fake Poop — yes, edible. The reveal where you pick it up and eat it is worth the entire batch.
- How To Make Fake Vomit & Puke — the dried-realistic classic, plus what to actually do with it once you’ve made a convincing puddle.
Special Effects & Movie Magic
Level up from gross-out to genuinely impressive. These are the projects that make people ask “wait, how did you DO that?”
- How To Make Three-Ingredient Slime — no borax stress, works every time, endlessly satisfying. The gateway project for kids and prank-scientists alike.
- Vampire Drink Blood — when you want the drinkable, theatrical version rather than the DIY batch.
Chemistry-Set Chaos
A little kitchen science goes a long way. Handle these with the usual grown-up care — we flag the safety notes in each guide.
- How To Make A Stink Bomb — the safe, household version of the world’s most persuasive “leave the room” device. Ventilation required; faces off-limits.
- The Amazing Dyed Shower Prank — turn someone’s morning rinse into a tie-dye experience, the wash-off-able way.
Surprisingly Useful “Fakes”
Not every fake is for a prank. A couple of these guides get searched by people with entirely practical problems — and we’re happy to help.
- Fake Ultrasound Pictures To Use — for the ultimate announcement gag (or April Fools’ masterpiece).
- How To Remove Skunk Odor — genuinely useful science for a genuinely terrible day. The one page here you hope you never need.
