Picture of Disco Ball Helmet

Why make a disco ball helmet?  Because it's awesome.  Nuff said. 

I've seen disco ball helmets before, but they didn't satisfy the perfectionist in me.  No haphazardly glued plastic mirror pieces here, this is the real deal.  If you would like to make a proper disco ball helmet, read on. 

• Note: This disco ball helmet uses real glass, as it is intended as a costume piece (to be paired with a disco backpack, coming soon!).  If you want it to be functional, acrylic mirror would be safer and lighter weight (though not as shiny and reflective).

Step 1: Supplies

You will need:

Mirror tiles: I used mirror tiles that come backed with fabric.  This makes the whole process MUCH faster.  You can purchase it from Kit Kraft.  I had quite a bit left over, I probably used one half to two thirds of it.  They also sell mirror tile by the row, but it's still more cost effective to buy the sheet.

Contact cement: I just barely made it through with one bottle.  I would recommend getting two.

Helmet:  I spent a lot of time choosing what kind of helmet I wanted.  I settled on this vintage Bell motorcycle style because of it's spherical shape and clean lines.  Real bell helmets of this style are quite expensive, but you can find cheap knock offs on ebay.  Search for "vintage open face motorcycle helmet" to find a helmet similar to the one used here.

Glass cutter (not pictured): For cutting the tiles to shape along the edges of the helmet.  Easy to get at a hardware store.

Metal Saw (not pictured):  Most of the vintage style helmets have snaps for a visor which need to be removed.  There may be another way to remove them, but I happened to have a jeweler's saw handy which did the trick.
Where did you find that information? I've seen helmet instructions that reccomend polyurethane paint.
Hi, sorry, new to this site, so have posted my reply separately below
Any water based paint or glue should be fine too I'd imagine.
It all hinges on whether the substance used will lead to crack propogation. I for one would not like to find out that it does when involved in an accident.
Your arre correct, polyurethane paint is o.k. but only polyurethane paint. I got the information from when I worked in the motor industry and one of the vehicles we manufactured had polyurethane 'bumpers' which were painted body colour, but the paint was not polyurethane. The smallest bump resulted in the bumper splitting in two. Polyurethane paint does not crack and thus does not propogate a crack. Most, if not all, other paints do crack and thus cause a problem. I have seen video of a polyurethane crash helmet that had been painted in some other paint than polyurethane dropped on the floor and it just shattered. It was obviously of no use in an accident.
I wonder how many people here read the instructable...
This might be the case. I wonder if the mirrors would just come off the fabric? If it is real glass then there is another concern....shrapnel.

Looks so perfect!
I do some deejaying and did the same thing once with a pair of headphones.
I used an old discoball(...) yes, one by one... every lttle mirror...
So if I'll have to make one again, I surely do like you and buy the sheets :)
I used a superglue 'cause I wanted to make sure that I won't have a bag full of little mirrors and a lot of bold spots on my phones, haha.

Those are awesome, thanks for sharing!

LOL PEOPLE!!! She Plainly states this is for COSTUME not practical use. It is for fun not to blind people.
Aha..... you are quite correct. {:o)
Mind you.... I'll bet a good few would want to ride with it and look real cool.
I guess in reality, fools will never listen to sense, and those with brains would figure it out for themselves, eh? {:o)
She also plainly states:

"If you want it to be functional, acrylic mirror would be safer and lighter weight (though not as shiny and reflective)"

Most snaps of this style are put on with blind rivets. You can usually just drill inside the snap with a drill bit slightly larger than the rivet and the head of the rivet will let go, allowing you to push it through the other side.

Thanks for the tip!

This is a disco helmet done right - nicely done.

Where do you see yourself wearing it most? Around town, on a motorcycle, at a new years eve party?

Are the seems between the tiles smooth? I'd envision myself touching my dome head a lot.
Natalina (author)  noahw2 years ago
So far I've worn it to parties and snowboarding. And once I get the party backpack done, it will be awesome at burning man or halloween!

And yes, the seams between the tiles are pretty smooth, although there are a few less smooth areas around the edges.

Very impressive!! Here are your shoes to go with it: http://www.instructables.com/id/DIY-SEXY-MIRROR-SHOES/.
Now we just need to make you some disco pants!  Maybe BetaBrand can hook you up in exchange for some awesome photos like these!
Natalina (author)  scoochmaroo2 years ago
Nice!
Awesome look. Problem is most knobs in cages still won't see you, so don't worry for a second about "blinding" them. If it gets even a little of their attention away from jabbering on their phones like magpies or texting (I guess they feel that their car knows the way home) then it's a job well done. Might be a good notion to mirror-out the middle finger on one of your gloves, too.
Absolutely. Anything to wake them up out of their trance. I wouldn't even worry about using this "costume piece" on the road. If you're in an accident where this helmet is struck, you're going to have a lot more to worry about than a few small pieces of glass.

All the Yes in the world! I'm very tempted to do something similar

Glass for costume, Acrylic/polycarbonate for actually riding with,

A rudimentary knowledge of the optics of reflective spheres for anyone saying "OMG WTF BBQ U blinzorxz me!"
A sphere, or faceted sphere is not the same as a plane mirror of the same size.
People will not be blinded by driving behind someone wearing a helmet like this any more than they are blinded by the chrome sidelight pods on a vespa.

Alas it also won't make an immense difference to rider visibility.
Better than black, not so good as plain white or yellow.

I would also be concerned about reflections of sunlight blinding other drivers. Otherwise, great looking helmet.

Unless you're quite tall, it might have been nice to finish the top using a similar technique.
I love anything wacky, and think this is great... BUT.... as a Old Greaser who's been riding for some forty-two years, (and I'm a Fully Certified Nutter at that, so believe me, I'm not known for my caution) I beg you or anyone making this not to actually use it whilst riding a bike. Slide down the road wearing this and you'll be in a world of broken glass.... Believe me, your eyes and face at the very least won't thank you for it.
As a fun thing and maybe a party thing or whatever.... great stuff.
PLEASE don't feel criticised.... I mean well. {:o)

it seems to me that people here just look at the pictures and don't actually read the instructable. This is a COSTUME PIECE, not meant to be functional. "This disco ball helmet uses real glass, as it is intended as a costume piece (to be paired with a disco backpack, coming soon!)"--straight from the instructable's text.

marry me. we'll make our children wear these helmets.

Cool project. Don't worry about the haters. A little touch of polyurethane over the glass would take care of the "shrapnel" danger. The helmet is round, so even the headlights of a tailgater directed back to that driver's eyes would be minimal. Most states allow morons to ride without helmets. Great costume! Use it around town on special occasions - it deserves to be seen!

I was a little concerned about safety too, but they make chrome helmets also and they are legal. There's nothing wrong with riders being more visible. All the whiners would understand once they've been hit or had a close call by a motorist who wasn't looking.
Artistically cute but did you ever consider how dangerous the helmet now is to you and others on the road? You will be blinding others from reflection of sunlight. I give you a week on the road before you are issued a ticket. Let us all hope you don't kill someone while using it.

Great looking helmet. Perfect for disco parties. Not so good for crashes. The last thing I would want as my head bounces along the pavement is 1000s of glass chards in the mix. Again, great look!!

I love it but if I was a car driver anywhere near ya I would hate you
dksmall2 years ago
Although it's a great looking helmet, I would also be concerned about the sun reflecting off this helmet and blinding people in traffic.

Most awesome! Also looks like the model is wearing a jacket from Betabrand..
bitza20092 years ago
Nice... do you gonna sell that..?
And this would really be worn in public, or is for those private moments when no one is around?

I wouldn't want to be behind you on your scooter/motocycle/etc. on a sunny day. You'd likely blind me.
This is the single greatest invention on instructables! I laughed so hard. well done.
