How To: Launch a Cork Rocket with an Ultraviolet LED Flashlight

Rosenberg, who's a research assistant and lecturer for the Natural Science division at Harvard, demonstrates what happens when hydrogen and chlorine are explosively "burned" together t...

Chromebook: The World's First Web-Only Laptop Computer Coming Soon

It's been about five months since Google first unveiled their prototype future computers running Chrome OS, and the time is nearly here for the Chromebooks to be unleashed on the public. But there are a lot of qualms over the release of Chromebooks, with most criticism coming from their lack of traditional laptop-based features such as an optical drive, storage space and the ability to run comprehensive software programs like Adobe Photoshop.

How To: DAVID GOLD on How to Make Alotta Millions from 99¢

Being a true cheapskate, I've long worshiped the iconic 99¢ Only Stores and its legendary and late-blooming founder, David Gold. Gold ranked in the Forbes 400 back in 2004, but didn't launch his empire until he was well into his 50s. And just last month, his extended family and private equity firm Leonard Green offered to take the retail chain from public to private—for $1.34 billion. Curious about Gold's unorthodox road to riches, I interviewed him and his wife Sherry at Los Angeles's public...

How To: Get Rid of All that Space Junk

How about a laser? One that is strong enough to nudge debris out of earth orbit. That's what NASA contractor James Mason wants to do, and his lab simulations suggest that the idea is possible. Mason wants to use a 5kW ground-based laser and a ground-based 1.5 meter telescope to spot potentially hazardous space waste and shove it off, by about 200 meters per day of lasering. It's kind-of like air traffic control for near earth orbit.

News: Zoetrope + Bicycle Wheel = Cyclotrope

Kudos to student Tim Wheatley, who came up with this incredibly nifty DIY animation using a bicycle wheel, cardboard cut-outs, and wire to create a magical reinvention of the classic zoetrope, Earth's earliest form of animation (it first surfaced in China around 180 AD!). Simply give it a spin, and the animation comes to life. Inspired to make your own? First, learn the basic principles of the zoetrope here or here. Next, take a little advice from Tim to add the "cyclo" element:

News: A Simple Semi-homemade Trick for Dressing

Here's something that I use to boost the stove top type stuffing mix. With Thanksgiving approaching, I thought I'd share it. The mix is often as cheap as the croutons for stuffing and it already has pretty good seasoning so I don't mind using it. However, what it lacks is the vegetable content that good stuffing should have. What I do is add the classic veggies to hop up the mix. Ingredients1 box of stuffing mix1 tbl Butter2 rib Celery finely chopped1/3 Medium Yellow Onion finely chopped1 tsp...
