KMnO3 Incendiary
1) pottasium permanganate (KMnO3) find at pharmacy
2) flowers of sulpher (S) find at pharmacy
Add KMnO3 to S in ratio 3:2. Shake to mix well. When shook for 1 min pour out and light.
About 50 grams should make a white flame about 0.5m to 1m high. I once poured water on it about 10sec after main flame had died out. It made a huge bang when it came in contact with the water.
