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 flames come 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.
