STROBING PROPELLANT #1
SOURCE: John Steinberg
COMMENTS: Strobe rockets function similar to strobe stars in that the reaction oscillates between flash and smolder phase. This formula can create different colors by replacing the barium sulfate with various other metal sulfates.
DANGER/CAUTION
Copper sulfate can NOT be used in this formula to produce a blue strobe. Copper sulfate readily absorbs moisture from the surrounding atmosphere. This moisture would then cause the magnesium and ammonium perchlorate to react, producing heat, and eventually spontaneous combustion.
PREPARATION (parts by weight):
| CHEMICAL | PERCENT/PARTS | AMOUNT |
| Ammonium perchlorate | 0.600 | |
| Barium sulfate | 0.150 | |
| Magnalium (-200 mesh) | 0.235 | |
| Magnesium (100 mesh, flake) | 0.015 | |
| Potassium dichromate | +0.100 | |
| Petroleum jelly | +10% | |
Total | ||
NOTE: +10% is 0.100 x batch weight
(For example: 0.100 x 200 g = 20)
