I used the half-opened bottom of a mixed-nuts tin over the current tube, and got a nice bang. Quite distinct from the whoomph. Very cool. Replicates earlier experiments and observations.
I hot-glued the defunct lighter into the shorter tube, so it looks like
a gun. That goes whoomph and spews a fireball. Nice. With the anti-silencer (ie half-opened can on the muzzle), you get a nice boom instead of a quiet whoomph. Will have to experiment with aperatures vs. acoustics.
Even cooler: after you fire it, the muzzle continues to burn off residual fuel.
Glows blue. Nice.
