Why does styrofoam float so well?
Styrofoam floats so well because it is made of a lightweight, closed-cell plastic called polystyrene. The air pockets in the polystyrene trap air, which makes the material less dense than water. This means that it will displace less water than its own weight, causing it to float.
The density of styrofoam is about 0.02 grams per cubic centimeter, which is much less than the density of water, which is 1 gram per cubic centimeter. This difference in density is what causes styrofoam to float.
Styrofoam is also a very strong material, which makes it resistant to breaking or tearing. This makes it a good choice for use in a variety of applications, such as packaging, insulation, and flotation devices.
