Not Telling
Hi, i know flash powder mixtures are sensitive to static electricity with some types more than others. My question is: if you have a firecracker from cardboard tube with sealed both ends, that contains a sensitive flash powder mixture to static, and you shake the firecracker, so you feel the powder moves inside the tube, can the friction of the powder and the walls of the tube generate static electricity inside the tube and ignite the flash powder? Are there any chances for this to happen? What if you have a plastic tube instead of cardboard?
Please replay only if you are sure about the answer. Thanks.
