The hair-growing cactus

[danbob6]

I ran across this cactus during my recent visit to the Seattle Conservatory. They don't like visitors touching the plants, so I wasn't able to determine whether the 'hair' was soft or hard and wiry.
The cactus itself stood about 5-6 feet tall.

Cool pic. Just from the looks of it, it looks soft to me.
