Step 2: Cut Hole in Top of Hat for Disco Ball

First detach the disco ball from the "motor part" that spins the ball (it should pop right off).

You'll see the "motor part" is circular, and will have a slightly indented smaller circular portion at the top.  You will want to cut a hole in the top of the hat just slightly smaller than this "top circle."

If you cut the hole the right size you'll be able to pop the "top circle" through the top of the hat and it will fit snug enough to hold the entire "motor part" up.

I agree with marolyn about the light source of your hat. That's cool but you should keep your instructable here and not link to another site with information that should be here so we don't have to do a run around
Where is the light source coming from for the ball?
in the vid, it looks like 2 laser pointers from above the hat.
Im going to use this for my halloween costum im going to put the disco ball in my hands because im creating a party Robot, but its not like a bunch of squares, im shaping sheet metal to make me look like the guy in the new video game coming out soon. Vanquish
 Neat!  If you went all out you could produce a room full of seizures!
I agree. I have epilepsy and have to shield my eyes from flashy things. If I was under the hat though I would be creating them, not getting them :)
How about setting your next hat to open the top and have the disco ball lift out from the hat when you push the button?<br />
I like that idea... an interactive disco ball ...
