Years ago, I posted a video of my version of the t-shirt launcher project. Recently, I retrofitted that cannon to shoot ordinary flour, which is then ignited, producing huge fire balls. The great thing about flour is that it is not flammable unless it is aerosolized, making it much safer than most other fuels. This could be a great platform for some kind of flame-belching pumpkin or other Halloween prop.
