Don't Spill Your Coffee While You Walk!
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.
t's always good to see science being used for something practical!
