Holding a mug by the top may not make it the easiest to drink from and could result in burns from the steam, but it does keep the mug’s center of gravity relatively stable in a normal walking motion. [Physicist Jiwon] Han also found a similar stabilizing effect came when he had his subjects walk backwards while holding the mug by the handle.
“Since the magnitude of acceleration in the claw-hand model is significantly smaller, the claw-hand posture is less likely to spill coffee,” Han writes. “Since we are not accustomed to backwards walking, our motion in the walking direction becomes irregular, and our body starts to heavily rely on sideways swinging motion in order to keep balance.”
