People do. It's not rare that someone will use ether, because it's rather powerful.

I think I've got a comparable can of "Easy Start" which seems to be mainly ether.

Theres posts about it being used as spudgun propellant and it seems to work fine.

Good to know, I'll try for my application. I'm currenrtly designing a large launcher. I'm thinking about using a fuel injection system off a car. it should give me a good fuel mixture. Basically it involves atomized fuel, that is compressed. Wont be using plastic though, going to go to our machine shop and use the cnc mill. Alos thinking potatos maynot hold up to the pressure, might make wood shells.
