This is an interview with NASA Langley retired researcher Donald Humes. Don was involved with research on the possible effects of meteors and other space debris on space craft. His research started when little was known of meteoroid protection. It was not until years later that Mr. Humes saw actual craters on space craft and was able to correlate his research with the reality of debris striking satellites and other space craft.
Research at the time used a light gas gun. These proved to be very expensive and did not meet the speeds required for meteor studies. Don was instrumental in developing a small gun with projectiles reaching the required speeds. This interview covers his work and views of the gun that he developed.
For more on the NASA Langley facility where this work was conducted, see http://crgis.ndc.nasa.gov/historic/1275.
This is one of the most, if not the most, powerful handheld cannons on Youtube. While I am sure there are more powerful cannons using black powder or such, rarely are they handheld. This cannon, which is basically an advanced form of a homemade spudgun, is capable of out-performing most commercial firearms due to the amount of muzzle energy it produces.

This is a project I have been thinking about for a while. My thought was that the hot light gas (normally hydrogen) used in normal light gas guns could be generated in situ with a charge of low-N nitrocellulose. My equilibrium calculations showed that such NC, when compressed to detonation by a second charge reaches approximately 3000 K, thousands of bars and very large volumes of gas. The low mean molecular weight and high temperature gives a theoretical maximum velocity of above 2000 m/s.
I used KClO3 / K3[Fe(CN)6] (https://www.youtube.com/watch?v=Cv0SZZyGgyA) for the compression charges. It's an exceptionally fast-burning mixture, but it still lacks the ability to detonate. This makes it the perfect choice in this case.
Even though a relatively low velocity (540 m/s, 1950 km/h, 1210 mph, 1770 fps) was reached, the prototype was a fantastic success. With a 40 mm long barrel, 540 m/s means an acceleration of 3.65 million m/s^2. That is as much as 1/5 of the acceleration in a real light gas gun, and many times higher than in conventional weapons.

"Space is the boundless three-dimensional extent in which objects and events have relative position and direction.[1] Physaical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. In mathematics, ""spaces"" are examined with different numbers of dimensions and with different underlying structures. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework.
Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the Timaeus of Plato, or Socrates in his reflections on what the Greeks called khora (i.e. ""space""), or in the Physics of Aristotle (Book IV, Delta) in the definition of topos (i.e. place), or even in the later ""geometrical conception of place"" as ""space qua extension"" in the Discourse on Place (Qawl fi al-Makan) of the 11th-century Arab polymath Alhazen.[2] Many of these classical philosophical questions were discussed in the Renaissance and then reformulated in the 17th century, particularly during the early development of classical mechanics. In Isaac Newton's view, space was absolute—in the sense that it existed permanently and independently of whether there were any matter in the space.[3] Other natural philosophers, notably Gottfried Leibniz, thought instead that space was in fact a collection of relations between objects, given by their distance and direction from one another. In the 18th century, the philosopher and theologian George Berkeley attempted to refute the ""visibility of spatial depth"" in his Essay Towards a New Theory of Vision. Later, the metaphysician Immanuel Kant said neither space nor time can be empirically perceived, they are elements of a systematic framework that humans use to structure all experiences. Kant referred to ""space"" in his Critique of Pure Reason as being: a subjective ""pure a priori form of intuition"", hence it is an unavoidable contribution of our human faculties."

Aloha fellow scientists! Have you ever seen anything so cool? So after watching NightHawkInLight's video I knew I had to do this. It was easy to do, all I needed was a TS8000 torch, and 10 feet of 7/8 tubing from the hardware store.
Inspiration for this video NightHawkInLights video - https://www.youtube.com/watch?v=jXoqw-_uDx4
The torch is self-igniting, meaning it has an electric sparker built in. When the button is pressed halfway, the torch mixes a perfect combination of propane and air into the tube. When the button is fully pressed the torch sparks sending a flame flying through the tube.
I tried to color the flame with some boric acid, and it turned bright green. NightHawkInLight gave me the idea to try powered charcoal to shoot embers and orange flame, worked great!
Well this experiment was not explody enough for me, so I used the same concept to build a propane powered cannon. This is honestly the best gas cannon I've ever used, it is just so simple. You could probably shoot 20 golfballs a minute the length of a football field or farther. The canon shot golf balls over 600 feet in the air!!
Im sure you can do tons of other cool things with this concept, let my know if you want me to try something!
Plans for the cannon - http://imgur.com/aIvOtPj
Different torches, and if they will work - http://imgur.com/a/w6Ji8
---------------------------------------------------------------------------------------------------------------------------------------------------------------
One important thing I forgot to mention in the video is the fit of the object in the barrel. If you completely plug the barrel the gas mixture does not enter the tube, because torch only 'passively' blows the mixture down the tube into the combustion chamber. All the projectiles i shot had some 'slack' in the barrel.

If you followed me on social media, you would have gotten sneak peeks for this video!

The light-gas gun is an apparatus for physics experiments, a highly specialized gun designed to generate very high velocities. It is usually used to study high speed impact phenomena (hypervelocity research), such as the formation of impact craters by meteorites or the erosion of materials by micrometeoroids. Some basic materials research relies on projectile impact to create high pressure: such systems are capable of forcing liquid hydrogen into a metallic state.
A light-gas gun works on the same principle as a spring piston airgun. A large-diameter piston is used to force a gaseous working fluid through a smaller-diameter barrel containing the projectile to be accelerated. This reduction in diameter acts as a lever, increasing the speed while decreasing the force. In an airgun, the large piston is powered by a spring or compressed air, and the working fluid is atmospheric air. In a light-gas gun, the piston is powered by a chemical reaction (usually gunpowder), and the working fluid is a lighter gas, such as helium or hydrogen (though helium is much safer to work with, hydrogen offers the best performance [as explained below], and causes less launch-tube erosion). One addition that a light-gas gun adds to the airgun is a rupture disk, which is a carefully calibrated disk (usually metal) designed to act as a valve. When the pressure builds up to the desired level behind the disk, the disk tears open, allowing the high-pressure, light gas to pass into the barrel. This ensures that the maximum amount of energy is available when the projectile begins moving.

Even though a relatively low velocity (540 m/s, 1950 km/h, 1210 mph, 1770 fps) was reached, the prototype was a fantastic success. With a 40 mm long barrel, 540 m/s means an acceleration of 3.65 million m/s^2. That is as much as 1/5 of the acceleration in a real light gas gun, and many times higher than in conventional weapons.

This is a project I have been thinking about for a while. My thought was that the hot light gas (normally hydrogen) used in normal light gas guns could be generated in situ with a charge of low-N nitrocellulose. My equilibrium calculations showed that such NC, when compressed to detonation by a second charge reaches approximately 3000 K, thousands of bars and very large volumes of gas. The low mean molecular weight and high temperature gives a theoretical maximum velocity of above 2000 m/s.

"Space is the boundless three-dimensional extent in which objects and events have relative position and direction.[1] Physaical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. In mathematics, ""spaces"" are examined with different numbers of dimensions and with different underlying structures. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework.
Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the Timaeus of Plato, or Socrates in his reflections on what the Greeks called khora (i.e. ""space""), or in the Physics of Aristotle (Book IV, Delta) in the definition of topos (i.e. place), or even in the later ""geometrical conception of place"" as ""space qua extension"" in the Discourse on Place (Qawl fi al-Makan) of the 11th-century Arab polymath Alhazen.[2] Many of these classical philosophical questions were discussed in the Renaissance and then reformulated in the 17th century, particularly during the early development of classical mechanics. In Isaac Newton's view, space was absolute—in the sense that it existed permanently and independently of whether there were any matter in the space.[3] Other natural philosophers, notably Gottfried Leibniz, thought instead that space was in fact a collection of relations between objects, given by their distance and direction from one another. In the 18th century, the philosopher and theologian George Berkeley attempted to refute the ""visibility of spatial depth"" in his Essay Towards a New Theory of Vision. Later, the metaphysician Immanuel Kant said neither space nor time can be empirically perceived, they are elements of a systematic framework that humans use to structure all experiences. Kant referred to ""space"" in his Critique of Pure Reason as being: a subjective ""pure a priori form of intuition"", hence it is an unavoidable contribution of our human faculties."

Aloha fellow scientists! Have you ever seen anything so cool? So after watching NightHawkInLight's video I knew I had to do this. It was easy to do, all I needed was a TS8000 torch, and 10 feet of 7/8 tubing from the hardware store.
Inspiration for this video NightHawkInLights video - https://www.youtube.com/watch?v=jXoqw-_uDx4
The torch is self-igniting, meaning it has an electric sparker built in. When the button is pressed halfway, the torch mixes a perfect combination of propane and air into the tube. When the button is fully pressed the torch sparks sending a flame flying through the tube.
I tried to color the flame with some boric acid, and it turned bright green. NightHawkInLight gave me the idea to try powered charcoal to shoot embers and orange flame, worked great!
Well this experiment was not explody enough for me, so I used the same concept to build a propane powered cannon. This is honestly the best gas cannon I've ever used, it is just so simple. You could probably shoot 20 golfballs a minute the length of a football field or farther. The canon shot golf balls over 600 feet in the air!!
Im sure you can do tons of other cool things with this concept, let my know if you want me to try something!
Plans for the cannon - http://imgur.com/aIvOtPj
Different torches, and if they will work - http://imgur.com/a/w6Ji8
---------------------------------------------------------------------------------------------------------------------------------------------------------------
One important thing I forgot to mention in the video is the fit of the object in the barrel. If you completely plug the barrel the gas mixture does not enter the tube, because torch only 'passively' blows the mixture down the tube into the combustion chamber. All the projectiles i shot had some 'slack' in the barrel.
