Flash string is very similar to flash paper. It appears to be ordinary white cotton string, but it is highly flammable. Ignited by your favorite method such as a match, candle, cigarette lighter, or other flame source, this string burns incredibly fast and leaves behind no traceable ash or residue. It has been used by magicians for years to produce a flash which turns into an appearing cane, silk hank, rose, etc. Included is an ample supply of string, about seventeen feet in length.
