I saw that TED talk, good on you for watching TED
you can make a bunch into a cheap necklace,
bend it around and make miniature art deco pieces,
clip paper,
make it into a tiny projectile with a rubber band,
use it like a mini football and flick it between your friends goal posted fingers
unbend it, and use it to poke questionable materials
do a hard reset on a tamogatchi
poke tiny holes in things
pick locks
(I know the TED talk said how you should change your perception of what constitutes a paperclip, but in the interest of fairness I didn't think of that when I saw the video, so I won't use it now.)
