A phrase I have uttered frequently with chinese two strokes and a stihl chainsaw with a wasp nest in the exhaust, usually followed by a handful of blisters.
Just about anything uses propane as a propellant nowadays. Even pit spray will make a satisfying bang.Friend of mine made a spud gun from PVC and a twist igniter, using carb cleaner in the chamber. It was so powerful that it knocked nails out of the boards on the back of his garage.
I discovered that when I sprayed olive oil on a BBQ grate, I was expecting a flare up but not that big, I read the can later and found propane was the propellant, lost my eyebrows and looked strange for a while and the source of much mirth in the court system.Just about anything uses propane as a propellant nowadays.

oxy-acetylene. Put a spark plug thread on the end of a ten foot length of fence post. Fill the pipe with the oxy-acetylene, insert the spud, and trigger the spark plug.Carb cleaner, WD40, and even women's hairspray worked pretty good. (Propellant?) Fire them at night and watch the flamescome out of the barrel.
A wonder we didn’t get killed.

In 1975 and I was 15, my older brother the electronics whiz gave me a Heathkit stereo receiver kit. A whopping 15 watts per channel. After a couple of weeks sorting and soldering dozens of resistors, capacitors, and transistors it didn’t work. I shipped it to the same brother to fix it. He has never let me forget it. I still have it somewhere.In 1964 I ordered a Knight Kit KG-636 oscilloscope kit from AlliedRadio. If I remember correctly it was about $100-$150, paid for with money from my paper route.
Took me a couple of weeks to assemble, and it worked the first time I turned it on. In fact I still have it and it still works. I used it a few months ago so trouble shoot an an audio problem in avionics panel I'm building for a friend's home built plane.
