Engineers Have Finally Figured Out How to Walk With a Coffee Mug Without Spilling!

#1.)  Start your walk slowly.  You don't want to accelerate too fast, that gets the liquid moving too much.

#2.)  Leave a gap between the top of the coffee and the top of the mug.  They say it should be at least one-eighth of the mug's diameter.  Since you're NOT going to bother to calculate that, just leave about half an inch of space.

#3.)  Look at the mug while you walk.  That keeps your body focused and is the biggest key to preventing a spill.
