Why does it make a noise when you snap?

Question

me and my sister are just wondering...

Answer 1

friction

Answer 2

Friction dear, kinda like thunder from lightning without the electrical energy.

Answer 3

When your middle finger hits the ball of your thumb, it pushes the air between the two out of the way quickly enough to make a sound.  Physically, it's a collision between two bodies, with some of the kinetic energy of the bodies being converted to sound energy (kinetic energy of the molecules in the air).

Answer 4

For every action there's an opposite reaction. So when you snap (action), it produces sound (reaction).

Answer 5

gud question!

Answer 6

the friction between your fingers creates rub and then noise releases

Answer 7

You create pressure between your thumb and finger. Then you slide your fingers using enough force to break the friction the fingers have against each other (when they're smushed together).

The snap sound actually comes from your finger hitting the inside of your hand. You hit it with your finger with the force of all the pressure you've built up when you put them together and snap them apart.

Answer 8

i think its because ur bone joints clip by going up n down if thats what ur asking hope that helped

Answer 9

your middle finger hitting the ball of the thumb, put an obstruction over the ball of the thumb and it wont make the noise
