Here’s a double dose of practicality for science geeks and glowsticking enthusiasts. Traditional store-bought glow sticks have a short life span of about 12 hours (some a lot less than that). If you use these things a lot, the costs can nickel and dime you over time. They’re pretty useless after a day as well. If you’re interested in making your own glow stick, check out the LED tutorial below and also the “how to” on making your own large glow lantern!

Homemade LED Glow Sticks

Things you’re going to need: A razor blade (box opener), a regular glow stick, LEDs, and electrical tape. The LEDs need to be those little keychain micro-lights. I’ve seen them for as cheap as $4 if you look in the right places. Just make sure you can switch it on without having to keep it pressed down.

To begin, get the original glow stick and cut it off at the base using the razor. No need to activate it, just clean it out real well (don’t get this stuff on your skin). After you’ve got the shell of the stick emptied out and clean, you’re going to need to doctor it up. Use the box cutter or razor to cut two parallel incisions (see right pic).

After that, position the LED between the incisions previously cut. The light should shine into the tube when turned on. As you can see from the video, this is just to give the glow stick some room for the inserted LED. Tape up the loose ends and turn it on!

Making a Glow Lantern

This is such a simple and easy How To, it feels like a shame not to try it. Something like a glow lantern would look great in a room, or a pumpkin for Halloween, or place it behind your monitor for a cool backlit effect.

Materials needed: Matches, bleach, 3% hydrogen peroxide, and a jar.

Cut about 20 matches at the top to get only the match heads. Throw them in the jar and mix in 3 cap-fulls of hydrogen peroxide. One more cap-full of bleach will do the trick. Put the top back on the jar and shake. This setup will stay lit of hours! Watch the simple directions in action below.

But, will it blend?

Bonus points for blending, thanks Tom Dickson!

Like everyone, the death of Michael Jackson has been a serious shock.  Of course, when shocked, my first reaction is to mumble a lot of crass jokes about Boy Scouts and the like, but once it hit me that someone I grew up listening to died?  I have to admit, I’m kind of depressed.  A […]

I can’t think of one person who isn’t fascinated with the concept of weightlessness. Man has always dreamed of flying, and the zero-gravity situation of space makes this humanoid flight possible. However, you don’t really get to ask astronauts to perform stunts for you, unless you’re able to email the Japan Aerospace Exploration […]

Next time you get a big mug of coffee from your local coffee shop, don’t just give right into it and start gulping away. Not only will you spare yourself lots of mouth and tongue burns by taking your time, you might also get to see a little bit of creativity. If you’re […]

You know, I love how strange the Internet world is. A few days ago, a friend of mine linked me to a trailer for a heartwarming movie about a shark and an octopus who become friends. Actually, it’s Mega Shark Vs. Giant Octopus and they’re more like frenemies united in their declaration that […]

Obviously this isn’t a real movie trailer, just a spoof. But is there any time where movie trailers deserve spoofing more than in the summer action season? I mean, these are some of the biggest, dumbest movies you’ll see all year. Don’t you think that if someone could figure out a way […]

It’s been a long, hard week. Everyone I know is grumbling as we round the corner into the last day of the work week. They may not have jobs, they may have jobs they hate, they may be having problems with husbands and wives and kids. No matter what’s got you down […]

In 2007, Russian scientists made an incredible discovery. In the Artic, they stumbled across the little body of a month-old baby mammoth that had been buried in mud and preserved for over 40,000 years. Her skin and hair are still intact. Her bones and organs? Still intact. Little Lyuba is […]
