Answer 1

Hi dear friend,
It is much easier to blast an inflated Balloon by a needle than by a finger for the following reasons :
1. The tip of the needle is sharp so that due to its sharp tip, the needle may put a force on very small area , producing a large pressure sufficient to the pierce of the balloon whereas if we use finger to burst the balloon the surface area of the finger is very more and blunt. so the pressure will be less.
