Oh, and just for fun.

Assume that this is an ordinary living room -- 250 square feet (drat and drat...I let a square slip in above when I should have been in cubes. But anyhow!) Since we want to occupy the room, and we need space for the air to move (with that industrial-sized blower), let's arbitrarily say the candles occupy a mere 250 ft^2/2 /12' ceiling or 40.4 ft^3 -- which is close enough 1 one cubic meter, nicely enough.

The ordinary candle has a density of about 1 and weighs about 4 oz. With 1 million candles crammed into 1 cubic meter, however;

1 m^3 = a million cubic centimeters, so 4 oz/cc, or 113.4 gm/cm^3 ....just a little less dense than the core of the Sun.


So, yes...if these magic candles were still somehow ordinary wax, they'd stop wicking almost immediately and the wax itself would combust...but if they obey ordinary rules of density for matter the hydrogen in them would fuse and for a glorious nano-second you'd have a much hotter flame. Unfortunately, without robust containment that first moment of fusion would blow the super-wax blob apart.

I'd put the final yield no more than the low kiloton range. Be interesting to see if the first neutron release would be instantly fatal, however (I suspect, given the high percentage of fast neutrons in plain H-H fusion, that first particle flood would turn the contents of the room to plasma).
