How to make this giant Rubiks Cube. From about 10 feet away this thing looks real!!!

Step 1: Materials

From local Michaels:

- 1 pack of vinyl cling sheets (see pic)
- 1 Elmers 20"x30" foam board (about 1/8" thick)

From local hardware:

- 2+ rolls of 1" wide black vinyl tape
- ordinary electrical tape to fill out as needed
- double sided Scotch tape

Tools:

box cutter/Exacto, large straight cutting edge, small ruler

Step 2: How I Made It

Not that I can give a great reason for building one yourself, but here's how I went about it...

I started by cutting the foam board down into five 10" squares, then taped them together into a 5-sided cube.

To give it the look of individual cubes, I made a V-shaped groove along each face by cutting into the foam board with a box cutter.
Then I taped over each of the grooves, pushing the tape into the groove as much as possible. To make it better, I then cut the tape along each groove to split it, then I pushed it in again so that the two edges separated.

The stickers:
I measured my real cube and it was 55mm wide and each sticker was 15mm wide. So I scaled the actual width of my box by 15/55, coming up with 7.2 cm width for each sticker. I think this made all the difference in getting the proportions right. Then I stuck the stickers on with double sided tape.

There are multiple color layouts in existence, but I tried to make mine the same as the color layout of the original version :)

I thought of this costume because Erno Rubik is a Hungarian just like me and we even have the same birthday. Long live the Cube dorks!
