Once used as solid rocket fuel because the reaction requires no oxygen, sulfur and zinc react vigorously. The reaction with zinc produces flame and a near explosion. Sparks fly and smoke billows in this dramatic chemical demonstration. Please DO NOT try this one at home.
Old newspapers come in handy for many different uses around the house, from birdcage liners to shipping cushioning and even a little fish cooking. But for backyard rocket scientists like Markus Bindhammer, they're more suitable as an ingredient for rocket propellant. Video: . ...more
Cooking isn't something that interests me much, unless it results in a fast burning fuel and a successful rocket launch! WARNING: Ignition of an incendiary or explosive material may not be legal in your area, so check local laws before attempting. Use of this video content is ...more
Move over NASA— SpaceX is taking over. Well, not really. But today, the privately funded spacecraft company broke all expectations when their Dragon capsule fell to a soft landing in the Pacific Ocean, completing an undoubtedly successful demo flight of nearly two full trips ...more
This week, I've been working on a project that sort of takes a spin off an old-style potato gun. Using PVC pipe and the rapid combustion of hairspray, we can launch a rocket hundreds of feet into the sky. As usual for my projects, I tried to use only materials and parts that a ...more
See how you can build a liquid fueled rocket with office supplies, mainly... a Sharpie magic marker and some duct tape. You'll also need some gas duster, the air cleaning can of gas. It's a pretty simple rocket to build, won't take long, and is loads of fun. Except, you'll nee ...more
Ever wondered what the inside of a burning rocket looks like? Well, thanks to Valve engineer Ben Krasnow, now we know. He built a homemade hybrid rocket engine that's see-through so you can actually watch how it works. And even though it's probably a really bad idea to try thi ...more
If you have read any of my previous articles or viewed the many videos I have published, it's quite clear that I appreciate a good rocket or fiery projectile. The following video will certainly not lessen that reputation. Using very inexpensive and common materials, this vide ...more
This is a fun little how-to showing what happens when you put some baking soda and vinegar in a film canistar. Shake it up and see it blast off. Keep back though, or you'll stink like your homemade rocket fuel. Video: .
Here's a technique I used to whip up a batch of super cheap and easy to make smoke flares! WARNING: Ignition of an incendiary or explosive material may not be legal in your area, so check local laws before attempting. Use of this video content is at your own risk. Video: . Th ...more
We all have a general idea of what a pin-up looks like: Big, buxom hips, wild curves that render men speechless, finger curled hair, and the iconic red lips with cat eyes combo. Bread out of the mold by creating a pin-up look that's equally glamorous and sexy but with a slight ...more
In this video you learn to make a PVC rocket that can travel hundreds of meters high. You start off by cutting your PVC pipe 62 mm long. Next dilute some kitty litter in a bowl to make it damp to compress. This makes a plug. Plug the pipe with 1 cm of liter. Then you add the r ...more
Nothing to do this summer? Then spark things up with a little baking soda and some vinegar and make a tiny, working rocket. Best of all—you probably already have most of the materials and ingredients lying around the house. What You'll Need Test tube Three small cardboard tri ...more
A new study casts real suspicion on the possibility of life on Mars. Why? It seems the surface of the planet may be downright uninhabitable for microbial life as we know it. Over the years, and with research into life on other worlds, visions of extra-terrestrials and "little ...more
Unless you're a high-schooler building a nuclear fusion reactor, the hardest part of a science investigatory project often is coming up with a good idea. You want it to be cool yet feasible, novel but still useful. That's why Ai-ni Bautista's science project on making liquid ...more
The worlds of augmented reality and virtual reality are closely linked in many ways. That means it's smart for AR insiders to keep a close on new developments in VR. If you have been paying attention, you know that Oculus CTO John Carmack is one one of the most important think ...more
If you're like me, you were disappointed when NASA cut their human space flight program. No longer could children and adults in dead-end jobs dream of someday walking on the surface of the Moon or drinking floating globules of water through a straw. Homo sapiens as a species a ...more

The recent announcement that Facebook will begin inserting advertisements into its VR experience on its Oculus Quest headset has set the VR and augmented reality industry into a frenzy. At first glance, the first thing many will point to is the recent history of Facebook and ...more
A rocket stove is a "rocket" combustion approach to preparing meals, which provides high combustion efficiency and efficient heat transfer to the cooking pot. Research suggests (through practical experience) that by using a rocket stove, you could save at least 50% of fuelwood ...more
Most people who are really serious about rocketry prefer solid-fueled rockets, but if your passion is for water rockets, then this video should help you with your advanced eater rocket project. It will show you how to construct and troubleshoot a 9mm Gardena nozzle to control ...more
To build a stone rocket stove, you will need the following: stones, wood, a tender pile, and lighter (or something to start a fire) Gather large stones. A fire pit is useful. Make a base with the large stones. Place 2 parallel. Then, close the ends, by placing stones around i ...more
Thinking about building a rocket stove? A rocket stove is simply made and accepts small-diameter fuel such as twigs or small branches, yielding high combustion efficiency and directing the resultant heat onto a small area. In this video learn how to make a rocket stove with th ...more
The rocket stove, invented by Dr. Larry Winiarski, was developed to require much less cooking fuel than a traditional stove. The rocket stove also emits less dangerously, as most of the energy burned turns into heat. To build this rocket stove, you will need sheet metal or a 5 ...more
