DexMat Pi day movie final

Here we show off the difference between Pi grams of copper wire and Pi grams of our carbon nanotube yarn.

Full disclosure: some of the difference in length here is due to the carbon nanotube yarn being thinner. The copper wire in this video is 1.2 mm in diameter; the carbon nanotube yarn ranged from 0.7 mm to 1 mm in diameter. The length difference is so extreme, however, because of the difference in density between the two materials, which is close to a factor of 9.

Happy Pi Day!
