Picture of The Spilled Coffee Prank
Faux spilled coffee is an easy, realistic DIY prop designed to inspire panic and induce profanity.

Just look around. You're probably surrounded by irresistible, deserving targets: The fussy geek-of-a-roommate and his do-not-touch-my PC...  that annoying little sister (who wouldn't loan you 2 bucks last week) and her homework.  Then there's mom, who forces you to clean the whole neighborhood, (but really just your room) and her "Use a coaster, honey!" antique table.

You can literally punk anybody in your immediate vicinity... and here's how:


  • Choice of: styrofoam cup with a plastic spoon, drinking straw, etc.
  • Wax or parchment paper
  •  Wood glue
  • Contact cement
  • Chopped nuts- if you're making the sloppy spoon

  1. Put the cup on a small sheet of wax paper, turned on it's side. Be sure to use a flat surface.
  2. Squeeze a tablespoon of glue inside the cup, allowing some to spill out onto the wax paper.
  3. Squeeze a teaspoon (or so) of additional glue into the spoon and position it inside the cup. 
  4. Let air dry completely (and undisturbed) at room temperature. Mine took about 72 hours
  5. Spread a thin layer of contact cement on top of the dried wood glue. This gives the "spill" a wet look. It'll stay shiny even after it dries.
  6. Once the contact cement has dried, peel away wax paper... your prop is ready for punking!
Directions for Use:

As any great prankster knows, properly staging this tomfoolery will produce optimal, "WTF!" results.  It's preferable that you be glimpsed with the cup in your hand, prior to the punking. Then again, maybe not... if you want the victim to blame someone else. That's what I call a 2 for 1 prank!  >;-D <-BEG or Big, Evil Grin. (btw... is that emoticon obsolete these days?)

This spilled coffee cup can also double as a seat-saver.  Discreetly place on the tabletop in front of the seat or directly on the seat you'd like to save.  Offending interlopers will give it a wide berth.

You may also opt for The Sloppy Spoon Prank (sans coffee cup) as pictured below.  It's an equally effective prop that can be carried in your pocket, purse or glovebox.  Don't leave home without it! ;-)

Caveat: Due to the unpredictable nature of human excitabilty,  this prank may not be appropriate in the presence of priests, pets, grandmas or children with sensitive ears. 

hahahahha! Great idea! :)

i'm gonna try this thanks

I really loved that intro! I made something like this when I was nine, and planned on publishing an instructable on it, but yours is much more comprehensive and detailed. However, mine was intended for putting it on a seat so no one would sit there while I left. I really like what you did here!

How funny! When I was trying to come up with a name, I thought about "The Seat Saver Prank"!

Thanks for such a nice comment!!! :-)
Yours also looks way more realistic!

Would love to try saving a seat with this prank and viewing their face when the prop is picked up and casually placed in purse/briefcase, etc. Nicely done.
bajablue (author)  jmray2 years ago
I agree! I haven't been able to use these props yet, so please let me know if you do! ;-)

bajablue (author)  mprelle2 years ago
Hey BFF... the wood glue dries to a brownish-orange color and the overcoat of contact cement is tan colored.

Thank you for commenting!
