Why does a water balloon or paintball hurt so much if it doesn’t explode when it hits you?

Was wondering why this happens. I figured the ball exploding would hurt more.

The water balloon or paintball likely actually hurts more when it doesn’t explode, since exploding takes energy to tear the surface and send the water/paint flying in all directions – all the energy needed to do that means less energy being sent into you.

It’s a similar concept to cars: modern cars crumple when they get into an accident, which can look terrifying but all the damage absorbed into the car means less damage absorbed by the passengers inside. And if you’ve ever seen a person punch or karate chop a wooden board the same idea applies there too! Punching through a wooden board actually hurts less than punching the board without breaking it, since breaking the board means that energy from your punch is being absorbed and not all going right back into your fist.
