*Snaps to the pink panther theme*

I bet he used the reality stone to make that possible

The snapping sound of your finger is made by the impact of your middle finger on the inside of your hand. We only need to snap that way to create enough potential energy to make the noise, by using our thumb to create tension and speed for the middle finger. You can snap your fingers the heavyset winter gloves but the sound will be muffled.

Very educated, thank you
