Directed by Tina Keeper and presented by the National Film Board of CanadaHow Do They Recycle Steel? (1999) has everything: conveyor belts, crackling sounds, massive machines in a massive factory, sparks, smoke, fire, molten metal, more sparks…

Melting down and recycling existing steel products is a more efficient and sustainable process than mining iron ore to make virgin steel. From the EPA:

Recovering steel not only saves money, but also dramatically reduces energy consumption, compared to making steel from virgin materials. In turn, this reduces the amount of greenhouse gases released in to the air during processing and manufacturing steel from virgin ore.

Iron and steel are easily recycled and are the most recycled materials in the world.

There are more things that glow and more recycling in the archives.

In 2002, Brazilian engineer Alfredo Moser invented a simple way to bring the sun’s light indoors: fill a clear plastic 2 liter bottle with water and two capfuls of bleach, then make a hole in the roof and secure it with a waterproof sealant.

The result: 40 to 60 watts of free, natural light.

How does it work? The bleach keeps the water from turning green, and the water refracts sunlight. To see this innovative but simple invention in action, watch the the ecoideasnet video above (with captions on). Chilean Miguel Marchand helps to install the bottle lights, or Moser Lamps, in the home of a family that lives in the Andes.

Around 1.6 billion people — 25% of the Earth’s population — live without electricity, but with this simple idea, they can enjoy sustainable light in their home for free. Moser Lamps are becoming popular solutions in the PhilippinesIndia, Bangladesh, Tanzania, Argentina, Fiji, and other countries, and give an incredibly useful second life to plastic bottles.

Andy Knowlton finds reusable materials on the streets of Seoul, Korea, makes little dolls with the pieces, and then puts the dolls back out on the streets with a poem that he’s written, all to be discovered later by someone else. Such a great project… the 5 year old suggested that we make our own.

In February 2012, this O-I BJC state-of-the-art glass factory opened in Vietnam, just 60 kilometres south east of Ho Chi Minh City. Filmmaker Peter Scheid created a How It’s Made trailer for the company’s glass container manufacturing that features an excellent mix of seemingly endless conveyor belts and fast-moving orange molten glass gobs.

Watch YouTube user Xraise Cornell create a homemade horizontal vortex ring generatorWhen a small burst of air is released into a toroidal or poloidal vortex — essentially a spinning donut of water — it shapes the air into its own ring along the water’s trajectory, creating a vortex ring or a bubble ring.

While we have not made this invention (yet), it looks like a lot of fun. Or of course, with a lot of practice, you could try to make them with no materials at all, just like the dolphins do. Just remember to always be safe. Adult supervision is recommended when using tools or trying experiments underwater.

Or if you want to stay dry, try making a homemade vortex cannon with a tightly closed box with a narrow round hole at the end. Watch!
