One of the coolest things I have ever seen!

@Marty1fatbstard

Well done thanks for your effort and sharing.

@LenapeFireTurtle

Very very cool!! Even though it didn't lock in, it clearly shows how the pulses move back and forth... Very worth it indeed.

@adr0

amazing work

@hla27b

nice effort man
thanks for showing us the innards

@iEnergySupply

Thank you so much!! I am building a pulse jet with Tesla valves and wanted to see what it looked like inside roughly.

Good suggestions actualy. Preheating the glass and the engine will kill of thermal stress in the glass during start-up. Cilider sealing will take the heat (long enough) and makes sure that the glass stays in place. It'll also reduce vibration

@rustyoneone

have you considered using a polymer laminate to fuse multiple sheets glass together, what you (obviously) need is a more durable material or someway to form the glass portion to fit the cylindrical dimensions of the ignition chamber.
good idea

@yoonvh

@1metiz maybe if u heat the glass from the outside first, or together.
and something the put in between of the glass and the pulsejet, like sealing kit from cylinders. to maybe reduce vibrations a bit.
this could be stupid, i don't know. first time i see this. :)

@1metiz

@rustyoneone 

This test used 1cm thick glass, unlike the first one wich used 3mm thick stuff. The setup could do with some good heat resistant glass but I think the idea will work with this glass to. I just need to gently heat the glass so it won't crack due to the thermal stresses. It should at least be strong enough

@ollieoniel

coool

@RoboTekno

haha very cool :D

@austinober

you should use bullet proof glass or plexiglass or something

@LenapeFireTurtle

At first it seemed the air from nozzle moved the sparkler, but observing more one can see a wave carrying it out...Did I mention cool???

@ducttaperulestheworl

hey... if use alcohol instead of gas tank as fuel,maybe it'll look cooler :)

@1metiz

in this particular case, mostly shits and giggles. however, if this concept worked and you could actually see what happend in a working pulse-jet, recorded with high speed camera and in a professional setting, there could be much to learn about flow and perhaps acoustics. And it would look freaking awesome ofcourse :)

@rustyoneone

@1metiz 
jeezus, one cm you say..
well, never mind.
you know they say that somethings in life are
meant to be mysterious

@MacsCanfly

spud gun

@1metiz

exactly what you think it it: a sparkler :)
