While watching the Transformers behind the scenes featurettes, I came across this:

They have a PA tapping a piece of metal, and it's producing a perfect simulation of light reflecting off of moving water. Does anyone have any idea what this material is and where to get it?

Much thanks!

Mylar.

And i don't think that's a PA. It would be a grip's job to manipulate the Mylar. And he's wearing a tape measure... and some 2" Black Paper tape... ummm, i think he's a grip.

another great water gag is to have a shallow pool of water with the Mylar on the bottom of the pool. That looks awesome but is harder to focus than the 4'X4' frame.

you can get it anywhere where you get your expendables. It comes in 4' rolls like all the rest of it.

Oops.... Grip. I guess it's attached to a board of some kind? Or is it stiff enough to just wobble on its own? Thanks Frank!

it's stretched (loosely) over a 4'X4' empty frame.

Yes, it's mylar stretched on a 4x4 frame. The tighter you stretch it, the more "flat" the reflection. Stretching it more loosely and with mild wrinkles creates a more broken up reflection with more movement.

Is there something I'm missing that it's $20 and up for a roll from a production supply place and $4 a roll from an arts and crafts place? Are there different grades of mylar?

No, it's not all the same stuff. "Mylar" is actually a product name like "Kleenex" used generically to describe reflective polyester film.

It's available in different thicknesses, finishes, sizes, etc.

Is the stuff from arts and crafts stores 4 foot wide rolls? That could be the difference.
