Is there somethng like a firepit that I can have in my apartment during the winter that is a) safe and b) warm?
Well, it doesn't sound very safe! How big a fire are you intending on creating!?
I had a friend that had a coffee table that produced a blade of fire along one side. It ran off of liquid gas or something similar. His living room wasn't very big so during the winter it was very cosy!
I don't want to create a big or a dangerous fire. Just a fire for effect and also for a bit of warmth. I certainly won't be relying on it for heat during the winter.
