alternative uses for garage door rollers

We have a lot of creative people on here, so Lets have a little fun.

I work part time with someone installing garage doors, and He has piles of used rollers. I was thinking, what can these be used for?

I'm open to practical ideas, silly ideas, crazy ideas, pretty much anything.

I want this to be a fun thread.

Maybe find a way to bend the door track to make a mini roller coaster

Use them as wheels on wooden toys...?
Affix the stem into a drilled hole in a block of wood (1X4) and glue them to the bottom of old shoes for a roller skate.

I'm trying to refrain from saying "Sell them as scrap iron". Nope....won't do it..

use them an build a pull out bed liner, use them as casters, make drawer or shelf slides... a picture with the exact style and shape of hardware would be helpful to give more ideas.

Actually I think bc has a cool idea, with the rails and rollers flat instead of horizontal you've got a basic drawer pull, just make it strong or don't overload it
