Yeah, it will take a couple days to heal, but its not bad. I get burns like that a lot. I once touched the glass on a fire place that had been burning for a couple hours, that bruned 3 finger tips for a couple days.
Don't play with gas, lol. I have seen some big explosions. My nieghbor was trying to light stuff on fire, and he filled on of those large red plastic cups with gas and dumped it on the fire, it went up in a mushroom cloud about 10-15 feet high of fire, but he was fine, he did it a couple of times, before everything was lit good. I have also blown up a spray paint bottle in a fire. My friend threw it in from about 30 feet away, than we stood behind his caboose and peeked around the corner. I put a pair of safety glasses on that were lying there. That made a big boom and made a mushroom cloud of fire again, and we found the blackened can about 100 feet away. And finally, axe. The body spray, light a lighter about 6-12" in front of it, and spray. Thats pretty cool. And than the same kid, sprayed it all over a golf ball, lit it, and tosses it at his sister, and it burned so quick or something, it didnt burn his hand at all, or the rug it landed on.
Fire is fun, but dangerous.
