One option is to use strips of filter paper impregnated with a solution of potassium nitrate (it's such desperate).
Far better it is to buy a ready-burning fuse, eg ( Pyro - Jiva )
Low and vysokovoltová blasting
For low-blasting machine can use the parallel connected three batteries (approx. 14 V). Connection voltage source and a resistance wire (Kantal) made ??using bell wire (lead length is about 50 m - wants to try it).
For vysokovoltovou blasting machine is suitable assembly comprising W. generating alternating current, direct the use of semiconductor devices and liquid condenser. An easy way is to use the old field telephone. With such a blasting machine can easily reach 150 V, 3 A (peak). Length inlet bell wire may be about 300 m
