A colleague and I were just testing out our new big smoke-ring cannon,
which works beautifully (thanks for all the advice last spring, btw).

at a lit candle, but the rings didn't flame up. We knew they hit the
candle from the fact that it flickered, and we tried a variety of
proximities but nothing worked.
