Small balls made of styrofoam. Craft stores sell them in various sizes.
It depends. Generally, sizes up to 120mm are solid, and those from 140mm up are hollow.
Newton's cradle may not work as effectively with Styrofoam balls compared to metal balls, as Styrofoam balls are lighter and less dense. The lighter weight of Styrofoam balls could affect the momentum transfer between the balls, potentially leading to a less pronounced swinging motion in the Newton's cradle.
Huge Styrofoam balls can be purchased at Michaels craft stores either in store or online. Amazon sells huge Styrofoam balls online. Shape Innovation, Inc. sells Styrofoam balls and practically any size desired is available for order. They sell many sizes through Amazon but special orders should be placed directly through calling them to avoid service fees. Their toll free phone number is 800-224-3036.
The property that separates styrofoam balls is their buoyancy. Styrofoam balls are lightweight and have air trapped inside, making them less dense than water. This causes them to float on the surface of water, separating them from denser materials that sink.

When Styrofoam balls are placed in boiling water, they will start to melt and deform because Styrofoam is a type of plastic that softens under heat. The heat causes the air pockets in the material to expand and the balls to lose their shape, resulting in a gooey mass. Additionally, the release of toxic fumes from the melting Styrofoam can be harmful if inhaled.

To create a solar system model using Styrofoam balls, start by selecting different sizes of balls to represent the sun and planets, with the largest ball as the sun. Paint or cover each ball with appropriate colors or textures to resemble the celestial bodies, such as yellow for the sun and various colors for the planets. Use wire or sticks to attach the planets to a base or to the sun, positioning them at varying distances to simulate their orbits. Finally, you can add details like rings for Saturn using thin strips of Styrofoam or paper.
The bag of stones is heavier because stones have a much higher density than styrofoam balls. Density is mass divided by volume, so the weight of the material is determined by the mass. Stones are denser and therefore heavier than styrofoam balls of the same volume.
