The science of fireworks explained: Chemical reactions at 1,000 feet – Los Angeles Times   Leave a comment

The science of fireworks explained: Chemical reactions at 1,000 feet – Los Angeles Times.

“The science of fireworks explained: Chemical reactions at 1,000 feet

A bona fide pyrotechnics experts explains the chemistry that makes fireworks possible
‘Everything you see in a fireworks display is chemistry in action’

All across the country, Americans will wrap up their Fourth of July celebrations by watching the sky light up with fireworks. If you’re going to be one of them, you have chemistry to thank.

Fireworks displays have become increasingly sophisticated and spectacular, but the chemical reactions that make them possible are pretty basic, according toJohn Conkling, an adjunct chemistry professor at Washington College in Chestertown, Md., and past executive director of the American Pyrotechnics Assn. Conkling literally wrote the book on fireworks — it’s called “Chemistry of Pyrotechnics: Basic Principles and Theory,” and it was first published in 1985.

As Conkling explains in the video above, all fireworks have two essential ingredients — a chemical that’s rich in oxygen (different types of these chemicals produce different colors when they burn) and a chemical that serves as the fuel (different fuels burn at different rates and temperatures).

“Without chemistry, you wouldn’t have the burning mixtures, Conkling says. “Without the burning mixtures, you wouldn’t have fireworks.”

Once these mixtures are made, they are packed into an aerial shell that’s about as big as a snowcone. This cardboard contraption has a pocket of black powder on the bottom, which propels the shell skyward. Inside the pocket is a time fuse that connects to a black powder bursting charge.

When the time fuse burns away and the bursting charge explodes, it ignites an array of “effect pellets.” These pellets — ranging from the size of a pea to the size of a marble — produce the colors and visual effects that audiences crave.

The entire shell fits inside a cylindrical mortar tube that points the package up toward the sky.

In the video, Conkling (wearing safety glasses!) takes a blowtorch to small piles of powder. A pile containing strontium chloride burns red, a pile made with barium acetate burns green and a pile with copper oxide burns with a blue tint. When “moderately coarse magnesium” is added to the mixture, the combustion produces white sparks.

“Everything you see in a fireworks display is chemistry in action,” he says in the video, which was produced by the American Chemical Society.

In an interview with the PBS program “NOVA,” Conkling said researchers are working to create fireworks that burst in colors like lime green, violet and hot pink. They are also trying to develop shells that will burst in the shape of letters, paving the way for pyrotechnic words.

Conkling’s childhood fascination with fireworks has propelled him through a career that produced eight patents. His work spans both military and civilian uses, but in his view, fireworks are valuable even when they aren’t practical.

“Fireworks make people happy,” he says in the video. “There’s something about watching the night sky explode in color and sparks and noise that I think gets really deep in the human soul.”

World-Class Hybrid Grass for the World Cup – YouTube   Leave a comment

World-Class Hybrid Grass for the World Cup – YouTube.

” Published on 26 May 2014

May 27 (Bloomberg) — Desso Sports Systems’ “Grassmaster” is the cyborg version of soccer turf: neither natural nor artificial but a hybrid. Artificial fibers are injected into the pitch, then natural grass is planted and its roots grow entwined with the fibers, anchoring the grass. The result: a more even and durable playing field. The system has been used in the Olympics and in NFL stadiums. Now it’s been installed at the Arena de Sao Paulo — the venue for the opening match of the 2014 World Cup. (Source: Bloomberg) “

NASA Releases Earth Day “Global Selfie” Mosaic of Our Home Planet | NASA.

NASA Releases Earth Day “Global Selfie” Mosaic of Our Home Planet

For Earth Day this year, NASA invited people around the world to step outside to take a “selfie” and share it with the world on social media. NASA released Thursday a new view of our home planet created entirely from those photos.

The “Global Selfie” mosaic was built using more than 36,000 individual photographs drawn from the more than 50,000 images tagged #GlobalSelfie and posted on or around Earth Day, April 22, on Twitter, Instagram, Facebook, Google+ and Flickr. The project was designed to encourage environmental awareness and recognize the agency’s ongoing work to protect our home planet.

Selfies were posted by people on every continent and 113 countries and regions, from Antarctica to Yemen, Greenland to Guatemala, and Pakistan to Peru. The resulting global mosaic is a zoomable 3.2-gigapixel image that users can scan and explore to look at individual photos. The Global Selfie was assembled after several weeks of collecting and curating the submitted images.

“With the Global Selfie, NASA used crowd-sourced digital imagery to illustrate a different aspect of Earth than has been measured from satellites for decades: a mosaic of faces from around the globe,” said Peg Luce, deputy director of the Earth Science Division in the Science Mission Directorate at NASA Headquarters, Washington. “We were overwhelmed to see people participate from so many countries. We’re very grateful that people took the time to celebrate our home planet together, and we look forward to everyone doing their part to be good stewards of our precious Earth.”

The GigaPan image of Earth is based on views of each hemisphere captured on Earth Day 2014 by the Visible Infrared Imaging Radiometer Suite instrument on the Suomi National Polar-orbiting Partnership (NPP) satellite. Suomi NPP, a joint mission between NASA and the National Oceanic and Atmospheric Administration, collects data on both long-term climate change and short-term weather conditions.

The Global Selfie mosaic and related images and videos are available at:

The Global Selfie is part of a special year for NASA Earth science. For the first time in more than a decade, five NASA Earth Science missions are scheduled to launch in one year. The Global Precipitation Measurement Core Observatory, a joint mission with the Japan Aerospace Exploration Agency, was launched in February. The Orbiting Carbon Observatory-2 is set to launch in July with the Soil Moisture Active Passive mission to follow in November. And two Earth science instruments — RapidScat and the Cloud-Aerosol Transport System — will be launched to the International Space Station.

NASA missions have helped identify thousands of new planets across the universe in recent years, but the space agency studies no planet more closely than our own. With 17 Earth-observing satellites in orbit and ambitious airborne and ground-based observation campaigns, NASA produces data that help scientists get a clearer picture of Earth’s interconnected natural systems. The agency shares this unique knowledge with the global community and works with institutions in the United States and around the world that contribute to understanding and protecting our home planet.

Old Bicycle Parts Become Brilliant New Bike Racks – CityLab   Leave a comment

Old Bicycle Parts Become Brilliant New Bike Racks – CityLab.

Innovative, creative and practical.

 

“Old Bicycle Parts Become Brilliant New Bike Racks

Recycling, Picasso-style.

Andreas Scheiger

Technically, turning bike handlebars and seats into something of a bull was Picasso’s idea first. But Austrian designer Andreas Scheiger’s brilliant interpretation of Picasso’s Tête de Taureau shows how all sorts of modern bike parts can become gorgeously functional.

Scheiger has created a whole series of these bicycle hunting trophies, which can hold anything from umbrellas to hats to more bikes. A few pre-made versions are for sale in his online shop, but he also shows those who are so inclined how he made them here.
