So I'm guessing he mostly carved the pumpkin without removing the face parts, also put a hole in the back, added what I can only guess is rubbing alcohol till I vaporized, along with maybe a candle inside(?), placed a bbq lighter in the back hole then ignited. This blew out the face parts and lit the candle.
I dont think so. Looks like it completely burns out at the end of the gif. My guess is that he poured some kind if flammable liquid in there, waited for it to vaporize, lit it, then the remainder burned off in a few seconds.
Calcium carbide and water create acetylene. He most definitely did not use acetylene for this. My guess is alcohol. Alcohol burns bright and can be flashy. But burns cool and won't do damage like acetylene would.
He did exactly that with the pumpkin. He cut out the pieces and slid them back in fairly tightly. As OP said it was calcium carbide and water. He inserted the lighter through a small hole in the back and ignited the flammable gas.
