Here is a quick tutorial on how to turn a mechanical pencil into a mini gun. Chronograph speed test: kinetic energy speed (m/s) speed (fps) Average 0.0847 J 22 m/s 72 fps Max 0.128 J 27 m/s 89 fps Don’t forget to check the 170 fps compressed air blowgun.
Hi everybody, I had a lot of request about selling laser ligthers… So after a small survey, the pre-orders are finally open.
Here is a video explaining how to make helicopter fireworks…
Strobe rockets function similar to strobe stars in that the reaction oscillates between flash and smoulder phase.
Do you like rockets and you are a bit bored of the orange combustion ? Here are some colored rocket propellant ! All parts by weight. Red Strontium Nitrate 50 Potassium Perchlorate 8 Parlon 18 Magnalium, 275 mesh 12 Charcoal Airfloat 5 Sulfur 5 Red Gum 2 Dextrin +5
Here is how to make colored smoke mix. In this video I show you how to make purple ones using rhodamine B. To produce color, the dye must be vaporized by the combustion heat and exit the reaction zone attached to the gasseous by-products where it will condense in air to re-form into solid dye […]
This is how to pick handcuffs. For this video, I chose to use a pair of Smith and Wesson M100 handcuffs with a double locking system.With this model, the double lock is set up by pushing the small bar with the other side of the key. Once double locked, handcuffs can’t be tightened anymore. On […]
Smoke mix is a composition designed to produce smoke upon ignition. A common formula for a grey/white coloured smoke device is a mixture of the oxidizer Potassium nitrate, and sugar. This formula has another very similar variant in which the ingredients are left in powder form and the granulated sugar is replaced with icing sugar. […]
Here is how to make a powerful compressed air blow gun with a pen. Speed test (+-0.25% accuracy chronograph): – Average: 40 m/s = 131 fps = 89 mph – Max: 52 m/s = 170 fps = 116 mph Kinetic energy (0.3g bullet): – Average: 0.24 J – Max: 0.4 J
Step 1 : Bend one of the paper clips in a way it can be stuck in the lock. Step 2 : Unfold the other one and make a small hook at the end of it. Step 3 : Insert the first one into the top of the lock and push it to turn the […]
