Nerf Material
Nerf foam is made from a solid, spongy cellular material. To produce it, polyester resin reacts with another compound in the presence of CO2 from another reaction. It is this gas that creates open pockets within the polyurethane that, in turn, make the material soft and light.

Famous quotes containing the word material:
“Who shall set a limit to the influence of a human being? There are men, who, by their sympathetic attractions, carry nations with them, and lead the activity of the human race. And if there be such a tie, that, wherever the mind of man goes, nature will accompany him, perhaps there are men whose magnetisms are of that force to draw material and elemental powers, and, where they appear, immense instrumentalities organize around them.”
—Ralph Waldo Emerson (1803–1882)
