Hey guys! I just wanted to ask if any of you knew a compound thats easy (and affordable) to make at home that is relatively small that would produce smoke. This smoke is in no way meant to harm or otherwise maim someone I just needed a compound to put inside my smoke grenade to mask my movements in games outdoors. The smoke can be any color and thick and I need alot of it. The compund for it would be great if it could fit in a soup can and activated by fire, liquid (i.e. water vinegar or something). This needs to produce smoke for at least 20 seconds and no longer than several minutes. Thanks !!!!
