Did you know there’s a way to start a fire by squishing air? In this project we’re building a tool that does exactly that, and with a little bit of resourcefulness, we can make this for under $1.00. This tool is completely see through, so you can witness the ignition first hand!

Project History & More Info:

A fire piston, or a “slam rod fire starter” as I sometimes call it, is a device used centuries ago to kindle fire. It works because rapid compression heats the air in the chamber to the ignition point of tinders, such as char cloth. The tinder can then be used to ignite kindling, and develop a flame.

It’s thought that the fire piston may have inspired Rudolf Diesel in his creation of the diesel engine around 1892.

I had a fire piston I made out of copper tubing, but I wanted to make one out of clear acrylic so I could actually see the ignition of the tinder. It seemed it mystery how, or when, it actually lit, and I wanted to see.

FINDING ACRYLIC: I used google.com to find different plastics companies in my area, and called around until I found one that sold acrylic tubing and rods to the public. I went for a visit, and luckily they had some lengths of scrap tubing they couldn’t sell. I asked them if I could use it for a science project, and they gave it to me for free.

The tubing I used was 1/2″ inside diameter, and the rod was 1/2″ outside diameter – clear acrylic.

This piston was given to a subscriber, as part of a contest I held in celebration of 10,000 subscribers on my YouTube channel.

It’s few flaws remain and with all new C7 model just around the corner, will GM finally fix the flaws the vehicle has always had? Stay tuned for our preview later next month at the 2013 Detroit Auto Show.

Today, it remains the companies best seller and most known model. Personally, we think the first generation has better driving dynamics but the second generation has a much more luxury car feeling interior. Hopefully, Infiniti will figure out how to blend the two with the upcoming third generation.

For this project I used items from around the house to create a pyrotechnic time-delay. Here’s how to make a simple form of a slow burning fuse, because when experimenting with homemade pyrotechnics, you don’t want to be too close if your composition explodes.

Project History & More Info:

Similar to the recipes I tried for rocket fuel and smoke flares in previous videos, I’m using a 60/40 mix of KNO3 and white table sugar by weight. This time I’m making a 60 gram batch, adding it to boiling water, and stirring it in until it all dissolves.

Fuses were homemade by soaking 12 feet of 100% cotton yarn in the solution as the rest of the water evaporated out, then placed on a cookie sheet and baked in an oven at 300ºF for 20 minutes.

These types of devices may not be legal to make or use in your area, so check local laws before attempting to duplicate this project, and as always, be safe and aware of your environment before igniting anything flammable!

A midsize luxury sedan that offers all the right sounds, balance, and handling expected from the BMW badge. At the same time, that badge means you will pay more for this car relative to it’s competition. If you have to go with a German brand, this car is the original and one of the best. At the same time, we’d recommend checking out it’s Japanese competition if value and lower ownership cost is more important for you.

Melt a stack of pennies, burst a glass bottle, damage various food items, and incinerate wood using the power of the Sun! This 4 foot magnifying lens will melt concrete, and nearly anything else that gets in its way.

WARNING:

This project should not be attempted without adult supervision and adequate training. Misuse, or careless use, of tools or projects may result in serious injury property damage, or death. Concentrated solar energy can start fires and cause personal and property damage. Concentrated UV radiation may cause blindness. Do not look directly at focal point without eye protection like welding goggles. Burning of metals like zinc, may release toxic gasses that can be harmful if inhaled. Extreme caution is advised.

Project History & More Info:

LEGALITIES: Some people have asked about the legality of treating pennies in this manner. The federal law states that there are exceptions made for use as “educational, amusement, novelty, jewelry, and similar purposes as long as the volumes treated and the nature of the treatment make it clear that such treatment is not intended as a means by which to profit solely from the value of the metal content of the coins.” For more information, see: https://www.federalregister.gov/articles/2007/04/16/E7-7088/prohibition-on-the-exportation-melting-or-treatment-of-5-cent-and-one-cent-coins

A 4 foot magnifying glass is powerful enough to melt metal, incinerate wood, and burn holes in concrete.

Putting that statement to the test with various items was the purpose of this project. I’m impressed at the results, and excited at the power available through this Fresnel lens that I’ve nicknamed my “Solar Scorcher”.

In the summer, the sunlight at this spot is around 2000ºF, maybe more. Enough to melt spots of concrete into glowing orange liquid.

I’m curious to see what I can do with all this heat so I’ve filled a glass bottle with water and I’ll punch a hole in the cap. It’s incredible to see that the instant I focus my lens on the bottle, it starts smoking. Just a few moments later this water is so hot it’s boiling, and I’m a little nervous the bottle might blow. Yep, there it goes. I’ll try burning a penny, and, wow, it melted. How about a stack of pennies? Yep, they’re nothing but liquid metal now, and I’m thinking that slag in the mixture must be what’s left of the copper coating. It’s only taking about 4 seconds to melt these.

Well, I’m convinced there’s an insane amount of power behind these lenses. If you’d like to see where I got this one, take a look at my video on how I hacked it out of an old TV.

This one boiled water in less than a minute, welded a nickel to concrete, and instantly torched any piece of wood in it’s way.

It was brought to my attention that Kipkay did a project like a couple of years ago that he called the “Solar Death Ray”. Check out his awesome video: http://www.youtube.com/watch?v=sAT6IRBK_uE

Project History & More Info:

These TV’s are old, extremely heavy, and are breaking down on people everywhere. They usually cost more to fix than they could be sold for, so people are begging you to come take them away for free!

I usually find mine on the classified adds under the “free” section, but they are also common on the sides of streets and alleyways where people have left them for trash.

PLEASE NOTE: These lenses are found in “rear-projection” televisions and not all are the same. Some are discolored, and some concentrate to a beam rather than a point. The particular screen I found was a crystal clear acrylic lens that focused to a point. It may have been luck that I found it on my first try, because 3 TV’s after that all had lesser grade lenses, but still produced enough heat to melt zinc. Just FYI! You can also see http://youtu.be/xExXjXm0YV0 for examples of these different lenses.

It was brought to my attention that Kipkay did a project like a couple of years ago that he called the “Solar Death Ray”. It’s probably where FenceKid got the idea, which in turn, inspired me. Check out his awesome video: http://www.youtube.com/watch?v=sAT6IRBK_uE

Honda’s Fit sub-compact essentially redefined the market and forced other automakers to catch up to their level. Now, in its third year, in its second generation, it would seem that the competition is breathing right down the Fit’s neck and Honda has some catching up to do. Luckily, the bones of this vehicle are still impressive and as soon as Honda smooths out the rough edges, they will once again have a class leader on their hands.

Like us on Facebook @ http://www.Facebook.com/2Redline Toyota’s Rav4 may be the original compact SUV, but being the original doesn’t always mean you’re the best. While the third generation may have been top of class back in 2006, today it is one of the oldest in the market. A potent V6 keeps things interesting, but it’s cheap and slightly snug interior may have you running toward newer competition.
