Good news! Things are working now. Thanks guys!

Another thing that works great is liquid oxygen, except it's not actually flammable but just allows flames to burn brighter.

The video I was attempting to share wasn't one of mine, but from another YouTube channel (the red hot nickel ball guy, not sure if you've heard of him). I tried another one of a haunted theater in Pennsylvania to see maybe if it was that his channel was banned or something (since I know the red hot nickel ball guy is kind of a meme due to his popularity he once had). The haunted theater video didn't work either.

Hopefully it's fixed now and I can submit the video. Thanks for looking into this!
