Version zero [point] two Mark 1138 for my mason jar pulse-jet tests.
The diffusion cone and the lid insert are now made of copper, but quickly slapped together.
While I knew it would burn away, I wanted to see the result if I welded the copper cone with electronic solder. Yes, it did burn away and the solder promoted the burning of the copper probably more than it would have.
I love how the copper glows orange in contrast to the blue of the flaming methanol. The flame is green in the beginning as that is due to the solder dripping down and taking some copper with it into the fuel. Once all the copper is burned out of the methanol, the flame goes back to it's normal blue hue.
Loading more stuff…
Hmm…it looks like things are taking a while to load. Try again?
