Everyday Design: Avoid leaks with this ultra simple coffee cup adjustment.

The lid on your coffee cup is a pretty amazing piece of design, but there's one thing that you can do to make sure it works properly. You might not even know it's leaking--until you'e wearing your finest!

I knew it the second i saw the seam on the cup. It always lines up with the spout.

So true! Always hate the leaky seam side.

This particular cup is a horrible design. Its not the spout, its the seam itself that causes the leaking. Any gas station cup is better than this.
