One of my favorite episodes of Rick and Morty features the giant floating heads, aka Cromulons, which run a galaxy-wide broadcasted television program judging the musical talents of different planets. But the basic point is that they're giant heads that yell (among other things) "SHOW ME WHAT YOU GOT!!!!"

For Halloween, I made this one out of:

cardboard
duct tape
packing foam
plaster wrap
tempura paint

People were asking me how I made it, so here's a write-up! Now you, too, can make your own Cromulon giant head to wear on top of your head.

Step 1: Frame

You'll need to make a frame for your giant head. It's possible to do this entirely out of cardboard, but I had some nice cushioning foam that had been used for packing material for my 3D printer. Duct tape holds it together nicely. Hot glue is also useful for fast cardboard-to-cardboard adhesion. Be careful when using it on other materials, which might melt or burn more easily!

You can see the evolution of the frame in the images here.

Step 2: Plaster / Papier-mâché

I went to a local craft store and found a bunch of plaster modeling cloth. (Here's an example from Blick, although it's not the brand I used.) It's a nice and light way to put down a hard layer on your mask-- just dip the strips in warm water and adhere them to the mask frame. I put only one layer of strips, shaping the mouth so that I could still see out of it and making the area on the nose thinner for increased visibility.

If you wanted to, you could use papier-mâché here instead, but I really loved the plaster strips. They were easy to work with and dried very quickly. I felt confident in their structural integrity after only one layer.

Once the plaster is down, wait for it to dry. (Or mostly dry, if you're me and you're impatient.) Then it's time to paint!

Step 3: Paint!

I mixed tempura paint for the base, mostly yellow with a small amount of orange and brown thrown in. At the last minute I decided it needed a little more of a rosy finish and added an extremely watered down layer of red acrylic. The pupils I also did in acrylic, since I wanted to have the most control over the dot shape.

Step 4: Attach It to Your Head

Or more accurately, your shoulders. I added two duct tape straps to the back of the frame and slipped them over my shoulders like a reverse backpack. You can also see that I taped a little dish towel in there so that my head wouldn't be pushed directly against the frame.
