It starts with a plastic known as styrene. Liquid or soft styrene has air or gasses forced through it, causing it to expand or foam up. Styrene+ foam= styrofoam. The material gets lighter as it foams up, and later solidifies.
One effective method to separate marbles and foam balls is by using the technique of sieving. Sieving involves passing a mixture of marbles and foam balls through a sieve with appropriately sized holes that allow only one type of object to pass through while retaining the other. By shaking the sieve, the marbles, which are larger and denser, will be retained while the lighter foam balls will pass through. This method takes advantage of the differences in size and density between the marbles and foam balls to achieve separation.
Foam
Foam rubber it is made up with a foaming agent for creating an air-filledmatrix structure. Those foam rubbers are normally either polyurethane foam or natural foam rubber latex.Foam rubber can also created from chemicals polyol,Latex foam rubber.Used in:mattressesInsulationFurniturePackagingCostumes

Yes, thermocol balls are made of expanded polystyrene foam, which is less dense than water. This is why thermocol balls will float on water.

you break them into or you add them.

Balls that are denser than water will sink. This includes materials like glass, steel, or rocks. Conversely, balls made of lighter materials like plastic or foam will typically float.
you could make it into a planet
yes, they do
It Doesn't. Actually the foam balls themselves has weight and therefore presses down on the vessel.
A stress ball is a malleable toy made up of foam. It is used to relieve tension and stress from the hands and fingers.
re-enforced rubber and a slim layer of some bouncy material American dodgeballs are made of rubber and pumped with air. where I'm from (the UK) we use foam balls with a hard plastic layer on the outside.
