Hodgdon Sporting Fuse is a flexible cord containing an internal burning medium, designed for applications where a delayed fuse is required. Common use is for firing canons in war reenactments.
Fuse is green in color, 15 feet long and 3/32-inch in diameter. Fuse is coated for waterproofing (with a water-resistant lacquer) and cannot be extinguished with water. Burn rate is 35 seconds per foot.
This will require a Haz Mat fee.
