Not disagreeing with @KinkyJ, holding it up where you can take a picture is a pretty bad chance of blinding yourself if it pops. Could be what you're seeing there, the gas is coming out of the narrower hole fast enough that the flame front moves away from the nozzle. That's unstable, though, and the flame front might get sucked right back into the lighter.<br />
<br />
Check online, you might find some advice on safer flame front experiments you can do. Enjoy, post pictures!

Thanks a lot! Yeah, i love to experiment. And that's easier now in the 20th century with all of this lighters, plastics, fridges, ovens, microwaves, independent light sources, computers, etc. It's just a jungle awaiting to be explored! Thanks for the safety advise, i'll take care next times!

A fascinating jungle, and a dangerous one. Think face shield -- always, always protect your eyes -- ear protection, long sleeve flannel shirt -- *not* synthetic fabric, ever! and sandbags. Oh, and a friend with a fire extinguisher and a phone to call 911. Have fun doing Science, don't forget to keep a notebook for Posterity.

Wow, pretty. I don't know why. You need someone in the sciences to explain that effect. <br />
<br />
Be careful, though, Kinky is right, it could blow up and do some serious harm.

Best Answer

Because it blocked the gas from escaping as designed...<br />
Clear it out or throw it out before it blows up in your face.

Best Answer

True. But it ignited after a time of being out in the oxygen, why's that?

Best Answer

because the gas was able to release around the wax even though it is being partially blocked.

Best Answer

Then why the whole trail of gas isn't ignited and just the little bit at the top? Because of the temperature of the wax?

Best Answer

That is where the gas was most concentrated, which means that the rest of the gas is expanding beyond it's designated area for which it was designed make it unpredictable and dangerous.
