Um. Not an engineer or anything, but those aren't paperclips. Retitle?

I used to use paperclips and rubber bands.

it looks like someone made a track out of a unraveled paperclip

Followed by 'making a microwave out of chewing gum and paperclips'.

Maybe he forgot the paperclips and duct tape?

There's a guy on youtube who demos how to do it using a paperclip hole in the section of the balloon outside your mouth---the art is in the slow, and unnoticed deflation.

Now I feel like MacGuyver. Add in a paperclip and a toothpick and we'll have an explosive device!

Cold would make a steel frame contract (a little) and make it more brittle / less malleable. But, it'd have to be *extremely* cold (like, liquid Nitrogen cold or beyond) to make it so brittle that it would be more likely to break before bending.

As a result of being merely natural environment cold (in liquid water so not less than 0 C) it probably was a bit more brittle (and therefore harder / less malleable) than the same metal would have been at higher temperatures. Maybe it took a measurable percentage more force to bend in those conditions -- but clearly not enough to prevent it from folding like a paperclip given the massive force on it.

Possible that I'm off on some or all of that, been a long time since Engineering Physics at Uni.

Why mommy can't sew!

Here's a pyro-aside this reminded me of:
U will Need:

paperclip
flint
butane lighter

bend paper-clip in such a manner as to hold flint in-place
with lighter, heat flint while holding the end of the paperclip far enough away from finger to avoid heat transfer-(flint will glow and swell twice it's size, at this point...)

Throw glowing flint & paperclip combination at hard surface, concrete, brick wall, etc.

Super explody white-sparkler-action, and really cool sound

There should be a name for this...
