8,000 views and counting! Keep 'em coming guys! I made 6 polumnas using cardstock and 2 grams of black powder each. The speed is 8x actual speed. I don't recommend lighting these in the garage unless the doors are open. (I have to do it or my neighbors get pissed) Depending on the quality of the black powder and how well the polumna is made, these can easily be loud enough to damage your hearing. Too often I find myself saying "Hello, hello, hello, phew!" after I light these. Please rate and comment!!!
