Space Blooms This January, NASA astronauts welcomed some new faces on the International Space Station: a colorful batch of zinnia flowers. Plants on the space station grow out of special pillows, not in pots like they would on Earth. NASA hopes that someday astronauts will be able to grow fresh food on long-distance flights. The astronauts have already grown lettuce in space. They even got to taste the leaves. But many fruits and vegetables are flowering plants. These are trickier to grow than lettuce leaves. So as a test, after the lettuce, the astronauts tried zinnias. The flowers bloomed beautifully on the space station. Since the zinnias were a success, astronauts will next try a tastier flowering plant: tomatoes. NOT SO FAST How fast was Tyrannosaurus rex? Scientists have found a new clue in a…

what a blast!

One spring day in Seattle, curious spectators gathered at a safe distance to watch the huge Kingdome stadium get demolished. Pop! Crack! Roar! In less than a minute, it was all done. New Walls for Old Although breaking up buildings with explosives might sound dangerous, “It’s really the safest and best way to bring a building down,” says Jamie Makin, a demolition expert. Knocking apart a building with bulldozers, jackhammers, and cranes takes a long time and many people. It can block traffic and fill the air with dust for months. A blast is over quickly, and cleanup can start right away. Using explosives to demolish a building doesn’t mean blowing it up. Instead, it’s collapsed. Like choreographers creating a ballet, engineers plan which columns and walls to knock out, and in what…

the kingdome toppled

BOOM... After everything was removed from inside the Kingdome, explosives were carefully set up to go off in a special order. Crack.... The first set of blasts cracked the columns around the edge and broke the ribs in three sections of the roof. Because there are metal bars inside the roof, it bent but did not break. And down it comes. The second set of blasts broke the rest of the roof sections. The weight of the roof falling pulled the columns inward, and the whole building collapsed. Easy as pie! A final round of blasts broke everything into smaller pieces for easy removal.…

stacey loizeaux, master blaster

Stacey Loizeaux has a blast doing her job. Her family runs Controlled Demolition, a company that uses explosives to take down buildings. So far, they have demolished more than 7,000. Loizeaux was part of the team that demolished the Kingdome. It took about a month to lay all the charges and get everything ready. Then it was all over in 20 seconds. Loizeaux still remembers her first job. “I was about three years old, and my family was taking down the Monroe Street bridge in Zanesville, Ohio. I got to press my finger on the button setting off the charge to bring the bridge down!” What’s it like to push the button? There is a series of loud cracks as the explosives go off. In a blink, the building begins to drop. Enormous…

exploding art

Cai Guo-Qiang (say his name Sy Gwo Chang) is a Chinese artist who likes to make art with a bang. He creates special fireworks shows, or “explosion events,” that mix fireworks and colored smoke to create pictures of beautiful flowers, or rainbows, or other interesting shapes. He also makes fiery paintings by laying thin trails of gunpowder in a stencil cutout, then lighting the trail under a protective cover. As the powder burns, it leaves a scorched picture behind. Cai likes the idea of using the sometimes destructive power of gunpowder to create art and joy instead. He also likes the way fireworks bring people together outdoors to share art.…

fantastic fireworks

Apyrotechnician—someone who works with fireworks—might say that a firework is a bunch of chemicals arranged so that they explode in a particular order. The main ingredient in fireworks is black powder—old-fashioned gunpowder. When a spark ignites black powder, it burns very rapidly, releasing a lot of gas very quickly. The force of all that gas pushing out is what we call an explosion. Fireworks are filled with small, hard pellets called stars, made of a paste of black powder and other chemicals that explode and spark. Hundreds of these small stars exploding make the colored, sparkly part of the fireworks that you see in the air. Fireworks makers use many different kinds of stars to make their fiery effects. To create a firework, the stars are scooped up and poured or packed into…
