ELI5: Why does the campfire smoke keep following me?
gpt
Hot air rises...So when your campfire creates warm air, it will rise above it...The cooler air around the fire gets drawn in towards the rising air...Because you are near the campfire your body blocks the path of the air heading towards the fire which causes lower air pressure and thus pulling the rising smoke and warmer air towards you...
