Demonstration of "Extreme DIY" in which the jet engine raises roar and the air cannon shoots a huge fireball

Unlike mere exhibitions, the real thrill is that at so-called workshop-type events, you can actually move your hands and make something and experience a lot. Little more, there is no reason not to be fun if "fire-blowing air cannon" or "jet engine" moves absolutely never before seen in front of you.

Chiyoda Ward's3331 Arts ChiyodaIn the experiential science workshop "Extreme Experiment" which was held at the end of the workshop, demonstrations of too dangerous works were carried out on the rooftop to finally move indoors, concluding the event.

Details are below.
The time is 18:00. It is about time the sun has set, the sky has become dark.


The stage will be transferred to the rooftop and a demonstration will be held.


First of all, demonstration of Mr. Takeshi Ogino's adult air gun "High Power Cannon". You can blow out flammable liquid such as gasoline like a water gun and ignite it to make a huge fireball and play. Ethanol was used for gasoline this time because it is too strong, but still a fireball of a reasonable size was generated.

Next is the demonstration of the jet engine. At first, I was at this position, but "At this angle the turbine blade might fly when it exploded in any case" I was asked to move.


I did not ignite it because the temperature of the combustion chamber was renewed and the temperature was low and the viscosity of the oil became high, but it did not ignite, but when the compressed air was blown by the compressor, the audience 's high turbine sound called "Queen!" Expectations also increase.

And finally it succeeded in ignition. It is spinning in red but raising roar and turning.

Producer Hiroshi Suzuki. With gas such as propane and butane, it seems that only "power not to run my bicycle" will be available, and next time I want to make a power source using liquid fuel such as kerosene. Moreover, as a further challenge, he said "I would like to make a rocket" and his ambition.
