Last time, our intrepid crew had just finished the build of the internal part of the maze, and had tested the flame effects during the day. Now it was time to test them at night!

Initial reactions were very strong:

Mirror Blaze Night Flame Test #1 (blurry):

Mirror Blaze Night Flame Test #2 “There is a lot of light.”:

Mirror Blaze Night Flame Test #3 (blue flame and backdraft tests):
I really enjoyed the blue flame in this video, and whenever it happened at the event. This set of tests were mostly us calibrating the length of time we needed to open the solenoid to get the optimal flame. If we set it off too quickly, there would be no propane in the accumulator, and we would get a small ‘foop’ flame. Setting if off for too long would give a slowly dwindling flame. The trick was the sweet spot in between.

Complicating this was the backdraft issue, where you had to have some air flow pushing the denser-than-air propane up the tube, or it would fall down and ignite out the bottom of the tube. In practice, we found that warm air (from an immediately previous ignition) was often enough to supply this airflow upwards:

Also note that the tube was starting to get sooty.

Hellblazer also got in on the flame action[1]!

Stay tuned for next time, where we strike camp and pack up!
