1. Using 10-20 teabags lined up in a row and lighting each one on fire one by one and having them float up into the air.
2. Film a fireplace burning then project that onto a TV then film a couple cuddling on a couch watching the fireplace on the TV in front of them. The finished piece would be a video of the couple watching their fake fireplace.
3. Use tealight candles to light a path starting from inside somewhere leading outside to show a larger fire.
