Step 1: Completely Scientific Requred Materials

Materials:

• Large Cardboard Tube (about 3" diameter)

• Small plastic jug (If you have trouble finding some, try the dollar tree cleaning aisle)
• Corrugated cardboard
• Thin cardboard (or card stock)
• 6 plastic bottle caps
• Long, cylindrical bottle (Try fancy expensive water bottles, they usually come in different shapes)
• Wire Coat hanger
• 1" strip of foam padding (I used a camping pad)
• A small lens
• Strong string

Tools:

• X-acto knife or box cutter (make sure you have a sharp one)
• Wire cutters (for the coat hanger)

Though I'm thanking you really late here (lol I forgot :P) I really appreciated you putting this up, I made my own chell costume on halloween :D
This was really clever and nice to make, really good that you used recyclables too!
I even got to shoot it at old people in a restaurant and security cameras. c:

Using the strips from postal envelopes is absolutely brilliant! Thank you so much for sharing this!

about how much would you say that fancy water costs and where did you get it?

[DucttapeNinja]

More than it's worth. I got mine from a roommate who was just going to toss it. I see them around in expensive markets and gas stations alike, if you're really set on buying one.

[conkay119]

is that kind of bottle really necessary or can i use something else instead?

[DucttapeNinja]

Something else is fine. Anything that will fit really. A bottle of smart water might work, or I've seen several bottles of a similar shape at Wall Mart. Maybe even try a bendable sheet of plastic. The spirit of this instructable is to work with what's on hand and (hopefully) not have to spend any money.

For what you had to work with that is pretty awesome.
Nice job.
