The average diameter of a ping pong ball is 40mm. I used this to calculate the area of the ball.
V=(1/6)(pie)d^3
=(1/6)(3.14)(40x10^-3)^3
=0.00003349m^3
=33.493333cm^3
1cm^3=1ml as a reference
If they float in water, then it is because the density of a ping pong ball is lighter than the density of water. The density of water is just below 1, and the density of a ping pong ball is much less than 1.
you can do a simple easy experiment to find the volume of a ping ball (water displacment). Place the ping pong ball in an amount of water with a known volume in a SI unit of volume (mL, liters). Notice the water has risen. Subtract the vslue of the original water from the new value of the water. This is the ping pong's volume.

A ping pong ball floats because it is less dense than water. The air trapped inside the ball creates buoyancy, causing it to stay at the water's surface.
Drop a big rock on the jar to smash it, thus releasing the ping pong ball. Fill the jar with water.

The hot water will soften the ping pong ball, causing it to regain its original shape as the material becomes more pliable. The dent should eventually pop back out as the ball absorbs the heat and expands.
To conduct a successful floating ping pong ball experiment, you will need a ping pong ball, a hairdryer, a smooth surface, and a container of water. The key steps include placing the ping pong ball on the water's surface, turning on the hairdryer to create an airflow over the ball, and adjusting the airflow to make the ball float. This experiment demonstrates the Bernoulli principle and the concept of air pressure.

It fixes the dent because the heat from the boiling water makes the air inside the ping pong ball expand, causing the dent to be filled out.
