Robot costume arms idea? Answered

I am building the robot below for a Halloween costume. I am building the head, upper and lower body, arms, and shoes out of silver painted cardboard. But as for the arms and legs I need advice as to what to use. I know the material used in these pics has a name but I am clueless as to where to find them and what it called. The costume should be flexible enough to dance (AKA wave my arms in a worm-like motion) at a Halloween party. Any tips or ideas?

Thanks in advance.

If you want I'll make an instructable once I figure it out and build it if you ask.

PS I am 5 feet 8 inches, and My arms are not too fat or too thin, and I am 14 years of age if you care.


They are use for the different systems, which is very helpful for us..

you should tell us more about it and also share some picture.

AWESOME!!!!! You've GOT to post pictures of the completed project. Bonus if you make an instructable. ;)

That is flexible dryer vent hose that you are looking for. Any hardware type store should have it.

That looks like the metal ducting they use to vent heating systems and gas fires.
