The fastest way to empty a bottle #shorts

Emptying the bottle is one of a trick. The main thing in emptying the bottle is how fast the air fills the space by replacing the water. When we emptying the bottle in a normal way the water resist the air from going into the bottle. Swirling the bottle makes the passage for air to pass into the bottle which increase the flow of water. To increase the flow of water we need to increase the flow of air into the bottle. The straw makes in every way to pass the air without any resistance hence increases the flow of water in a fastest way. #shorts #science #physics #education @CONCEPTUALGURUJI
