"Rope Fuse" is quite a simple type of fuse that lazily burns (or smolders, to be precise) at 1 to 2 hours per foot, possibly making it the slowest-burning "fuse" in the world. It's traditionally used at festivals or parties as a noisemaker; the fuses of dozens (or even hundreds) of small firecrackers like "Ladyfingers" are inserted into the weaves of the rope, causing the crackers to automatically ignite from every few seconds to minutes, depending on how many are used and how they are spaced.
Many Americans now use them on the 4th of July as a fun way to ensure that a nice "BANG!" rings out every so often throughout the course of a party or fireworks show. Our Rope Fuse is 3/8 inches in diameter and sold in lengths of 5 feet each, which will burn for about 6 to 8 hours if left uncut. At this price, you just can't lose for a product that will keep burning for an entire afternoon or evening!
