This dude is brewing some booze. This process creates gas and if you’re not careful with a fully sealed bottle they can explode. The gloves provide space for the gases to gather and a visual way to check the fermentation- if the glove isn’t inflating, something went wrong in that bottle.

He’s saluting them because he’s funny as hell.

He is showing respect
