How Do You Make Smoke Grenades (Red Dye)?
• Find a tennis ball or some hollowed out ball to use as a case. • Cut a slit into the ball big enough to fit items, but small enough to hot glue closed. • Fill the ball with ashes & black dirt, also add a firecracker. • Tie a medium length string to the fuse of the firecracker. Place it inside of the ball • Pour a small amount of red dye inside. • Seal using hot glue. Try to test it out on a non-living thing first.
