Glad you liked the story! Estes rocket motors generate their own oxygen therefore if you seal the nichrome with wax to make it waterproof you can fire the missile underwater! The wire does melt so you need a new wire for each firing. Some guys have even built exploding torpedoes which will actually sink plastic model surface ships or Skeedo Barbies! Lol Probably a silly question and I tried your color code and ended up with the first row of "X,s" and the remaining rows of just squares (no X's). Any idea what I could have done wrong?

Thanks, Ed
