I sent a cannon kit to a friend in New Mexico.
He is at pretty high elevation.
Here is his report.

"Binaca doesn't burn worth a damn, and getting a stochiometric mixture at
6750 feet altitude is impossible. The most we were able to get from it
was a gentle burp that wasn't even enough to separate the film can
from its lid."

Suggestions?

Some people have a hard time following directions and getting a
good fuel-to-air mixture even at sea level.

At my elevation (1600 feet), holding the Binaca about 2 inches
from the can allows enough air to become entrained in the spray
that the explosion is quite loud. Holding the Binaca close to the
can results in the experience related in the above message.

Have your friend practice at a lower elevation, and when he gets it
working, he can try again higher.

The cannon also has trouble in cold weather, where the vapor condenses
too quickly. Warming the can in your hands for a few seconds fixes
that problem.

Try feeding the film can with pure oxygen after spraying
the fuel inside the can.

I made three holes at the can's lid one for the wiregap and
the other for the oxygen intake pin(basketball pin),and the
other on for the gas outlet

Put 1 drop of your prefered fuel and then turn the oxygen
tank on i can't measure how many to put but try experimenting
with it. you'll need your own judging here just turn the
oxygen tank on and let some out at the third hole, when you feel
air coming out the third hole it indicates(maybe)enough air.
