You, too, can be a 360-O-saurus this Halloween

If you’ve visited 360 Live Media’s home office in the last year, no doubt you’ve noticed the large Tyrannosaurus Rex head hanging from the ceiling. That, my friend, was the grand-prize winner of last year’s 360 Live Media’s annual Halloween party.


And while the to-scale-dino-mask has generated its fair share of “oohs and ahhhs,” if you knew just how easy it was to make, you’d discover that’s truly where such exclamations were intended for.


Truth is, you can build one of your own, start-to-finish, in a single weekend. Heck, there’s only five components to it, and two of those repeat themselves.



Here’s how: 

1. First, print out the five-piece template (two jaw bones, two skull sides, and one spacer), included below.


2. Using an art projector, project the spacer onto a single sheet of 20” x 29” foam-core board or similarly proportioned cardboard.


3. Adjust the projector to Increase the size of the spacer on the foam-core until it is large enough to allow your entire head to fit comfortably between the four slots (1,2,A,B).


4. Using the felt-tip marker, outline the spacer on the foam-core, aligning the bottom of it with the bottom of the foam-core, leaving sufficient space for two jaw pieces to be outlined on the unused portion of the board.


5. Once you’ve identified the proper projector distance, use the same setting to project skull-side A onto a single sheet of foam core.


6. Using the scissors, cut out the spacer, setting aside the unused portion of the foam core to be used for both jaw bones (see step 9).


7. Using the scissors, cut out the first skull-side tracing (A).


8. Use the felt-tip marker around the newly liberated skull-side to outline an identical skull-side (B) on its own sheet of foam. Cut out the second skull-side and set both aside.


9. Using the art projector, project the jaw (1) onto the leftover foam-core from the skull-side A, positioning the sheet so that two jaws can be produced from the remnants.


10. Cut out the jaw outline and use it to trace and cut out the remaining jaw-side on the remaining foam-core remnant.


11. Once all 5-pieces are cut out, cut the narrow slits on the bottom of both jaws and skull-sides (no wider than a single snip of your scissors), as well as the slits on both sides of the spacer.


12. Now comes the easiest of the easy parts, simply slide the jaw #1 into the corresponding Spacer Slot #1, Jaw #2 into Spacer Slot #2, Skull-side A into Spacer Slot A, Skull-side B into Spacer Slot B, and voilà—you have a complete, human-scale T-Rex skull.



The only thing missing is the skin.  And for that, you’ll need a stack of discarded newspaper, cut into long strips and a batch of Paper-Mache. To make the Paper-Mache, simply mix 1 cup baking flour with two cups water, stir thoroughly until all the clumps are gone, and you’re done.


Now, strain individual newspaper strips through your bowl of Paper-Mache and drape over your newly minted dinosaur skull, being careful not to cover over the exposed teeth or, for that matter the opening for your head.


Let dry, paint—and next thing you know, you’re scooping up gobs of candy Halloween night, discarded by fleeing kids, unaware a ferocious T-Rex resided in the neighborhood.
