It might sound a bit brazen to play around with fire in an artificially oxygenated environment, but that hasn’t stopped the crew of the ISS from studying the behavior of flame aboard the orbiting science station. As Space.com shows us, fire behaves very strangely--relative to the way it behaves on Earth, at least--in mircrogravity, and the Flame Extinguishment Experiment (FLEX) has conducted more than 200 tests over two years to try and understand why.
Lance Greathouse does not follow football. It wasn't until last fall, at an Arizona Cardinals game, that the Phoenix dental-laser repairman, who harbors a severe DIY robot-building habit, was introduced to the art of tailgating. There, he spotted cars packed with grills, plasma screens, refrigerators and more. "But I never saw anything that was all-in-one," he recalls.

The U.S. Forest Service has battled fire with fire for nearly a century, but it wasn't until the past decade that backburning--in which professionals set brush alight before a wildfire does--became an exact science. Wildfire experts call this science prescribed burning, and its practitioners are known as burn bosses. Here are three increasingly precise tools to stop a wildfire cold.
The extent of my dedication to obeying the particular dietary rules of Passover is limited to two meals: The first seder, and a breakfast of matzah brei the next morning. I don't bother scouring the house for chametz (any bits of leavened bread, forbidden during Passover), because during the rest of the year I'm a big fan of leavened bread (it's delicious! Mmm, leavened bread) and I assume there's chametz all over my kitchen. But I wasn't aware that eradicating chametz could involve giant, high-powered blowtorches wielded by a rabbi described as being "built like a football player." Maybe I'll show more interest in the tradition next year.
It's all sweetness and light until the sugar hits the fan. In 2008 the sweetener killed 14 people in Georgia -- not from diabetes or heart disease, but in a violent explosion. Absence of regulation, ineffective enforcement, and lack of preparation for the potential danger led to the Imperial Sugar factory disaster, one of the worst industrial accidents of our time.
How is it that refill canisters for air horns costs four times as much as butane canisters? Ariel was not happy with the added expense and took matters into his own hands creating a butane horn with flames. While this is not his first butane hack, he has stepped into a larger world of noisy flame throwers. And if you think this duct-taped flaming air horn is a little shady, check out some of my other favorite flaming noise projects.
