Introduction: Bedroom Fx Ep. 2 Safe Smokebomb
This very simple smoke bomb needs not even the slightest spark. It only needs to be flung at a high velocity at something solid (like a wall.) so make sure your actor has one behind him/her.
you will need: easter egg, flour, and a spoon, (optional and not shown) slingshot.
put a couple of spoonfulls into the egg.
close it up, and chuck it.
P.S. be sure to use an old easter egg as it may crack.
