This whole effect is done by using a long exposure 'bulb' mode on the camera. you leave the shutter open for 30 seconds.
You cant put something burning in a jar as it will burn up the oxygen and then go out in a second or two. Plus there is a risk the glass will shatter
with the extreme heat of the burning metal.
The sparks only fly out because of the centrifugal force of the spin and more importantly a large amount of fresh air hitting them. When you sing the
whisk around on the end of a long wire its like putting you head out of a car at 100 mph..lots of wind and oxygen. It really doesn't burn well until
you get lots of oxygen flowing through it by spinning it around. If you dont get it spinning quickly after lighting it just goes out, you need the
equivalent of blowing on hot embers to keep it alight.
Ive been proved wrong before though , try it and post the results
