NEED A THIRD HAND? READ ON

The next time you need a third hand to hold your coffee cup while you dig around in your bag for something, just stick it to a streetlight with this ingenious hack.
A fabulously creative New York City blogger who goes by the name "AP" is all about devising clever ways to eat outdoors with flair. She's come up with ways to turn a lunchbox into a plate and a fire hydrant into a table, but we really dig her magnetic coffee cup holder.
It started out as an attempt to create a plastic, magnetized cup holder that would let you stick your cup to the nearest available metal surface. AP came up with a prototype, then had a thought:

After I made this I realized that it made a lot of sense to just work with a form that we are already really comfortable with: the Coffee Cozy. Why not just embed magnets into one of those?

You can easily make your own version of this by snagging reusable coffee sleeves online, or making your own. Attach a couple of strong magnets, and you're good to go.
