No, that isnīt any blowtorch...
Itīs just a small tea candle lightning inside. I was surprised too how much the pumpkin was lightning...I donīt know why but Iīm guessing itīs just because of the fact that is a quite small pumpkin, its sides are very thin and it also has a yellow coulour, so maybe thatīs why that shine is more conspicuous than itīs usual.
