Picture of head in a jar prank

Hungry? Scare those fridge-bound famished food foragers with a head in a jar!

Using a photo editor, two pictures are blended together to create flat image of a head, which is then laminated and submerged in a jar. When the flattened image in inserted into the curved jar, along with the distortion from the water, gives the illusion of a decapitated head in a jar of preserving fluid.

Here's what you need to make your own:

  • Photo editing software
  • Large jar
  • food colouring
  • printer + access to lamination service (local print/copy store)

Making your own head in a jar is easy, but requires some photo editing skills. I've included a tutorial on how I made mine, and took me about 30 minutes to compose. Personalizing this prank will make it more effective. But, if you're not a pro with photo editing, you can download my flattened head image below.

Step 1: Take photos + import

To make the head printout you'll need 2 pictures of a head, a profile and a portrait. With the camera at eye-level, take a picture straight on and one from the side. Ensure your subject is well lit. Also, ask them to make a face.

Next we'll import these images into a photo editing suite. Since the final output will be on a standard A4 / 8.5" x 11" printer paper, start by opening your photo editing software and opening a new document set to your printer paper size. Then, import the profile and portrait pictures of your subject onto new layers and resize them to fit your workspace. We'll resize them again after merging the faces together.

Step 2: Adjust levels + align images

Using your photo editor trim away any background so that you are left with just the face.

After trimming, if your two pictures have different lighting adjust the lighting levels (ctrl+L in most applications)

Using the eye as a level, align the two images so the features match up from the profile to the portrait (eyes, mouth, nose all aligned). Almost all photo editors have a ruler function, these help keep things true.

Hilarious. You can have your own room full of heads just like the Governor in the third season of The Walking Dead. LOL

It's a lot easier to use a real head. That's what I did.

My husband teaches eighth grade and I thought this would be the perfect April Fool's prank for him to pull in the teachers lounge. I took a photo of him with his face smashed up against a window and laminated it as suggested. We didn't have any food coloring on hand, so I used some yellow and brown Rit Fabric Dye instead. I also added a spoonful of flour and some bits of chicken for "floating debris". Cheap craft fur was added to look like hair, which was kept afloat by an empty plastic bottle place underneath.

The head made it's way throughout the school and eventually ended up in the closet of an unsuspecting teacher who was away for a few days. Thanks for the the tutorial~it was a hit :)

I think the face against the glass was a very good touch. Now if there was a rumor about him being missing.... I can see that this could be a great prank.

Ooh, the hair is a nice touch. Glad is spooked a few people.

Thanks for the membership and patch ;)

Having a huge forehead like mine made it problematic. I also had trouble finding a big enough jar. Definitely don't get one from Amazon...I had two of them arrive that sounded like maracas when I picked up the box, which made returning them simple, as I hadn't even opened them.

Your mighty forehead is what makes your head in a jar awesome :D

Pro tip: Choose a jar with a neck remotely large enough for a head to have been fit through in the first place.

I actually took three pictures, a separate one for both sides, so they are consistent with the lighting
€7.50 jar from Blokker
€4.25 printjob including lamination
A bit more green and a lot less blue food coloring than I intended.
Thank you for this awesome idea :D

Justin Bieber right where he should be. I used pixlr for my photo editing. The blending was tough, I mostly used the clone tool, and played with opacity for some blending effects. I'll let you know how the prank goes tomorrow.

How'd the prank go? LOL..

Tried using pixlr but couldn't get rid of the borders around each photo to merge the forward and profile together.

mikeasaurus (author)  lebowski5 months ago

The only good Bieber is a jar head Bieber.

cdi nova made it!3 months ago

I did it! Well, sort of..I cheated..didn't laminate or do water yet..not happy with my editing job so will continue to play when I have time...then go for the rest of the process.
