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:

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.

<p>Fun, will refine it, still offering Pro?</p>
<p>Ha, looking good. </p><p>Thanks for sharing a picture, enjoy the Pro Membership!</p>
<p>Oh my gosh now I have a great idea for next Halloween! Bookmarked!</p>
<p>Thanks for the gift mikeasaurus, sadly I'm not up to putting a light under water just yet. But with the help of the Instructables community I'm confident that will change. As the Supervising SGT. I did the read-out with the jar on the lecturn to the amusement of the nightshift. Sadly, due to a strict media policy i can't post any pictures of us in uniform.</p><p>thanks again mikeasaurus.</p>
<p>I had this on my desk at work over Halloween. It freaked the cleaners out so much I had to put it away. It's making a guest appearance for Friday the 13th, November. I don't think having a bald head works as well, but hair on my head just isn't going to be happening.</p>
<p>Looks amazing! And, is that a light inside, or just ambient glow?</p><p>I wouldn't sweat the details about hair, people see the big idea first and that's usually enough. Glad it worked out for you, hope you can scare someone again today!</p><p>Thanks for sharing your picture here, enjoy the Pro Membership!</p>
I did a quick and simple (not to scale) version using the PiscArt smartphone app for Android. Three mean-face selfies on a white background, blend pics, trim with scissors, place in a gallon size Ziploc bag, add water.
<p>Even with simple apps the effect is still good! I hope you scared some folks with your head inside the fridge :)</p><p>Thanks for sharing pictures, enjoy the Pro Membership!</p>
<p>these always make me <strong>sick</strong> ~ that's why i LOVE them!! <strong>x^)</strong></p>
<p>That is to cool</p>
<p>Worked pretty well for a headless man costume! People kept stopping to take pictures.</p>
<p>How do you get that backlit eerie glow in the jar? Anyone else have any ideas on that part please </p>
<p>I made 2 of these and found plain green food coloring works great. I also did a blue and it's not bad either. I used clear containers I had. If you use the wadeface provided, this is a 5 minute project but the results look like you spent much more time. </p><p>I can hardly wait for my grandson to open the refrigerator!</p>
<p>You can put the photo in a water tight bag. Then fill the jar with tonic water. it will glow under a black light. You can also use a liquid of choice and add vitamin B2 to it for the same effect. </p>
I used some inexpensive submersible led lights I got on amazon. It was a hit, and the light really helped the costume stand out while walking around in the dark.<br><br>here's something that would work - http://www.amazon.com/Submersible-Battery-LED-Lights~WHITE~wedding~tea-Light/dp/B000VUNXEY/ref=sr_1_3?ie=UTF8&amp;qid=1446222946&amp;sr=8-3&amp;keywords=submersible+led+lights
<p>Whoa, that costume is PERFECT!</p><p>Thanks for sharing a picture of your costume, Enjoy the Pro Membership.</p>
<p>This is really cool! Great idea :)</p>
<p>Great stuff! Love that eerie glow.</p><p>Enjoy the 3-month Pro Membership!<br></p>
<p>excellent r&eacute;sultat</p>
<p>Ha, that face is perfect!</p><p>Thanks for sharing your picture, Enjoy the Pro Membership.</p>
<p>I screwed up and left his collar on but it still turned out pretty cool... I'm going to do one taking a pic of the back of the head and print it on 11x17 paper... :)</p><p>I used water and some left over coffee...</p>
<p>Gory, and the brains are a great touch!</p><p>Thanks for sharing your picture, Enjoy the Pro Membership.</p>
<p>awesome, thanks for posting!</p>
<p>Its weird but looks good .</p>
<p>This was GREAT instructable for a quick to make prank since u were soooo nice to share ur pic. I put my work at eye level and in your face when u open the left fridge door. Sorry about the glare from interior light-photographer I'm not. Thanks again!!!</p>
<p>Where did you find this jar?</p>
<p>That jar came from Walmart and was originally a bulk purchase of sweet pickle chips. I haven't looked to see if they still have the glass jars in that size. It seems that plastic has become more prevalent. If not, I would try Sam's Club next. The glass is must soooo much better for the laboratory feel...</p>
<p>Update: Yes, they ARE Currently available at Walmart (at least in Central FL) complete with whole Kosher Dill Pickles for $5.22 a jar.</p>
<p>Being at eye-level, I hope it scared someone :)<br>Enjoy the 3-month Pro Membership!</p>
<p>Oh, it certainly did...bwaaahahahaha. &quot;Wade&quot; is positioned where cold beer traditionally sits...not what any of my empty-handed friends expected. Maybe next time they'll bring their own...teeheehee And thank you for the Pro membership! Bonus!!</p>
<p>The result are truly exceptional! If he sees a funeral director .... copy your idea!</p>
<p>brilliant, I absolutely love this.</p>
<p>I'm glad you offered up yours, because I have serious doubts that I could have figured all that out! Never used photoshop or anything of the like before. Thank you</p>
<p>That was absolutely great! I love the vid with the kids at the end. Thanks for such a good idea and excellent presentation.</p>
<p>Made this last year and doing again this year. A crowd favorite! Jar is from the Container Store; it's perfect.</p>
<p>You have an excellent dead-face :)</p><p>Thanks for sharing a picture of your head in a jar, enjoy the Pro Membership!</p>
<p>It worked out really well. People were really freaked and loved it. Thanks for the awesome idea. </p>
<p>Looks great, and that green color is really creepy.</p><p>Thanks for sharing a picture of your head in a jar, enjoy the Pro Membership!</p>
<p>This is such a great idea and love all the pictures posted in the comments. Has anyone tried smaller jars, like mason jars? (with different photo specs)</p>
<p>What about having a jar in a jar so the print is protected from the water?</p>
<p>That might actually work! If you use something like concentric beakers one slightly smaller than the other, put the photo in the inner one and only fill fluid in the space between the two. It'll take much less fluid, be much lighter, no lamination required and possibly give you the same effect.</p><p>Great instructable! Will try it out. Thanks!!</p>

<p>it would look like a jar with a head in it inside a larger jar with fluid</p>
<p>He said to laminate the print first.</p>
<p>Which doesn't render jtmcdole's question invalid.</p>
<p>But does render it irrelevant. It is of course possible, but would necessitate unrequired effort and the result would be sub par.</p>
<p>&quot;unrequired&quot; == &quot;optional&quot; effort if one doesn't have or care for laminating. You also have no standing to sugest it would generate sub-par results.</p>
<p>Keeping to being &quot;positive and constructive&quot;, look at in analytically: A jar has a much smaller mouth than a body. Wide-mouth jars will have a same-size or larger mouth than the base. To fit a jar in a jar, you must make the inner jar smaller than the outer jar...that's just physics. Thus, your &quot;head&quot; image will be smaller than a single jar alone. Further, you will be able to see both the inner jar and it's lid, breaking the illusion. Result: tiny head, in a jar, in a jar. Not a head-in-a-jar. Some of us have goofed around and have observed the real-world...which gives us some standing. Instead of whining about other commenters having no standing...just do it your way and post a picture. Not a proof, but a data point showing full-, partial-, or no success. Have fun with it.</p>
<p>Lol you guys are like having a buisness scientist argument thing</p>
