What happens if I set the things on fire together?

For a special movie effect, I'm trying to make a fire sort of smoke bomb. In the bomb I put, chromium, bleach, pine sol, comet, match heads,plastic shrapnel piece, graphite, men's cologne, active sunscreen, lemon juice(citric acid), flour, candle heads, candle oil, aluminum foil pieces, sandwich bag piece, wax paper, and the head of a cigarette. The smoke bomb is 4 1/2 inches, and 1.8cm wide, it is a cylinder and only the substance insert hole is about only 1cm wide, with the grenade pegs taking up 1 inch of the bottom area. So I only could insert roughly 4-9 grams of substances overall. It is very small, but I just want to know what will happen if I light it in a wide open field of cut grass? Will it start a small fire and smoke, or will it cause some wildfire? If you want to see what it looks like ask for my e-mail when you respond to this question. Thank you. Please help.
