Okay, I'm going to let you guys in on a little secret. The Nerf Ultra darts ARE made of styrofoam. But it's a little more complicated and it's actually a really strange story.

What everybody calls "styrofoam" is actually. A long time ago, in a galaxy far, far way DOW Chemical Corp trademarked a thick blue foam insulation board called Styrofoam®. It's still used in building materials today.

But for some reason, people started calling those white polystyrene cups, plates, and packing material "stryrofoam" because it kinda sorta resembled the texture of the blue Styrofoam insulation. But in reality, the cups, plates, and packing material are actually a different material made an entirely different way. Unfortunately the wrong name stuck. Like forever. So I'm willing to go along with the ruse and call it "styrofoam" for the sake of clarity.

So it turns out  polystyrene styrofoam melts. Those Nerf Ulra darts ARE made of styrofoam that's been heat treated until the outside layer melts and fuses together to create a smooth hard outside skin. When Coop snapped that Ultra dart you could see the internal styrofoam pellets and the hard outer layer that "cracked" when he bent it.

So kudos to everyone who suspected the Ultra darts were styrofoam. You may have gotten the name wrong, but you totally nailed it 👍
