    ...what sort of black magic is this

  • nice demo and great explaination 

  • Sounds like someone taking an epic shit like 3 times in this video. O.o

  • This guy needs a haircut I swear its gonna go up in flames

  • @IqsMontegro yes u did and thank you ^.^

  • @IqsMontegro so theres less concentration of it! so if u relate that concept back to the wax...there isnt enough wax to be burnt above where he put the match stick.!

    hope i answered ur question.

  • @THEGAMINGRULER because as the wax is cooling it dissapates into the atmosphere. therefore the molecules which make up the wax are spreading apart as it goes away from the source. A bit like if you sprayed some air freshner, you smell it for a bit, then it dissapates and fills the whole room up.

  • can some on answer this: why doesnt the flame go up when he puts it on the "smoke" after all the "smoke" is going up ?

  • 105 people never had birthday candles on their cake

  • @youtubasoarus Agreed, there definitely was more he wanted to share!
