an isoflex stress ball contains powdery sand.
I have one but you can't have it.
The Isoflex stress ball is a therapeutic tool designed to help relieve stress and tension through hand exercises and squeezing. It is often made from durable, flexible materials that offer varying levels of resistance, making it suitable for users of all ages.

Yes, search the web and you will find them for $2.75-$3.00.You may also bid on them at eBay or overstock auctions for cheaper.
a ball XD
Yes, air inside the ball has mass because air is made up of molecules which have mass. When air is trapped inside the ball, it contributes to the overall weight of the ball.
No ... the inside of a ping pong ball is filled with air. Click on the 'Inside of a Ping Pong Ball' link below to learn more.
Inside a golf ball can be many things. It could have a rubber ball, with rubber bands, and some have a cork and rubber
The ball will sink when the weight of the water inside the ball plus the weight of the ball is greater than the weight of the amount of water that would fit inside the ball.
Pumping pushes more air molecules into the ball. That makes more molecules moving around inside of the ball and more molecules colliding with the inside of the ball. All of those collisions (trillions and trillions) push the inside of the ball out. When the temperature is increased, the molecules move faster. Faster molecules collide with the inside walls more frequently, which also increases the pressure. You can test this by pumping up a ball then putting it into the freezer and see what happens to the pressure.
The inside of the ball becomes filled with the air you pump in, thus inflating the ball and turning it from a flat ball to a round one.
A sealed pocket of Air is inside the hollow center of a table tennis ball.
Heating a ball increases the air pressure inside, which causes the ball to inflate. This is due to the gas inside the ball expanding when heated, pushing against the walls of the ball and causing it to expand.
