This Nike Better World promo video from 2012 shares the manufacturing process of how plastic bottles can turn into “the most advanced football jerseys on the planet.” (And by the way, that’s soccer/football, not American football.)

There are some excellent vids about plastics and sports in the archives.

From National Geographic’s I Didn’t Know That, this flexible, concrete-laced canvas can be put up by two people and ready to use as shelter within 24 hours. It’s essentially a building in a bag. With water to activate the concrete and air to inflate it into shape, the concrete hardens into a solid structure that resists fire and water. It can even become a sterile, hospital-like environment, an essential need in humanitarian crisis situations.

From Household Hacker, How to Turn Milk Into Stone:

All we need for this simple kitchen science experiment is milk, vinegar and a strainer. You can make all kinds of shapes and designs using this “plastic-like” material. In fact, this is the stuff they used before plastic was around!

Instructions:
Take 1 warm cup of milk and mix with 1 tablespoon of white vinegar. Basically, for every cup of milk you use, add 1 tablespoon of vinegar and you can make a much larger batch. Mix it together and strain out the curds that form. Once you dry it you can mold it into any shape you desire, but let it dry for a couple days first!

The Gravity Stool thanks its unique shape to the cooperation between magnetic fields and the power of gravity.

Departing from the idea that everything is influenced by gravitation, a force that has a strongly shaping effect, Jólan intended to manipulate this natural phenomenon by exploiting its own power: magnetism. The positioning of the magnetic fields in the machine, opposing each other, has largely determined the final shape of the Gravity Stool.

It is the combination of the magnet machine with the plastic material, developed especially for this purpose, that enabled Jólan to start a small but efficient chain of production. The forms and products are characterized by the freakisch and organic shapes that are so typical of nature itself.

Thanks, @wizzyrea.
