this is a pretty good party trick. tip your head back and pucker your lips, then blow out to make a strong stream of air straight up. then place the ping pong ball in the air stream and it will float! tip: keep the air stream strong and constant and you should be able to keep it up for 4-5 seconds before gravity takes over.
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.
Put an exact amount of water in a measuring cup. Drop in a golf ball. The increase in water level equals the volume of the golf ball, assuming the ball doesn't float. For example, 200mL before ball. 280ml after ball dropped in. Therefore volume equals 40ml or 40 Cubic Centimeters.
#include<stdio.h> #include<conio.h> void main(); { float p,r,t; float ci(float,float,float); clrscr(); printf("\n enter principle\n"); scanf("%f",&p); printf("\n enter rate\n"); scanf("%f",&rate"); printf("\n enter time\n"); scanf("%f",&time"); printf("\n compound interest is%f ",ci(p,r,t)); getch(); } float ci(float a,float b,float c); float(result); result=p(1+r\100)^c-1); return(result); }
Check 21 is what eliminates float time
Use a straw to suck that ball Take it out from the other end of the pipe Use some sticky chewing gum on the end of a bit of string, or a cane - also handy for getting screws and things off the floor when you drop them down between things Fill the pipe with water and the ball will float out. Turn the pipe upside down Answer Use a vacume cleaner.
The pingpong ball will float on the surface of the hot water due to buoyancy, as it is less dense than water. The ball may expand slightly due to the increase in temperature, but will not significantly alter its shape or weight.

Cricket Ball yaar
There is no rubber in a soccer ball
Only because of the sound made when the ball hits the bat or paddle
A pingpong ball. There much lighter like if i throw them at my head with my shotgun it will not hurt much.
plastic , designed to be very light for hitting with a pingpong bat It is made of plastic
boil it in water, the dent should rise back up unless there is a crack
it is in fact regular air inside the ball. the smell is because its contained for so long the air has become stale.
float
A foosball out of those two would be more like a golf ball because it is quite solid. It is basically a perfectly smooth, hard plastic ball.
A dint in the surface of a pingpong ball can be removed by putting the ball in hot water. The hot water will expand the air inside the ball and push the dint out, restoring the original shape of the ball.As to a hole? A hole would allow the pingpong ball to fill with water.
