The Science of a Spill

Imagine your right hand holding a hot cup of coffee (no lid) and a heavy backpack hanging on your right shoulder. Then your bag suddenly slides down to your arm, which you try to prevent and counter its weight by pulling your arm up thereby spilling your coffee and eventually dropping your cup because your hand is burnt.

I imagined that too! That's why I walked very slowly so that won't happen.
