About
Paper Rocket Tubes, Fountain Tubes, Mortar Tubes, Fireworks Tubes What's the difference between a fireworks tube that is parallel (or "convolute") and one that is spiral? Well, they're made differently and it's easy to tell by the way the paper is wound. Paper towels or toilet paper are both wound parallel. But the paper tube inside them is wound spirally. So in making fireworks, when do you use parallel tubes and for what? Well, for some fireworks making applications, parallel and spiral tubes are interchangeable. But in general, parallel tubes are used to make fountains, rockets, whistles, hummers, and mortars. Chose a parallel tube whenever you want the strongest wall strength for your fireworks device. For instance, when ramming (hammering) rockets, you will want maximum wall strength. Skylighter offers a wide variety of parallel tubes for rockets in what are considered to be standard sizes. But if you need a shorter or longer tube, you may want to buy the uncut 24-36 inch tubes and cut them yourself, using any sort of saw. All tubes are natural kraft color unless otherwise noted. Dimensions are in inches, weights in pounds. I.D. refers to inside dimension. O.D. refers to outside dimension.
