I'm guessing this is a single father (or at least he is NOW) because there is NO WAY a wife and mother would allow her girls to HOLD roman candles like this while they're lit. This is obviously BAD parent, as the girls drop the roman candles once they start going off, and all hell breaks loose.
This video could've definitely ended A LOT worse than it did. Thank God.
