First, there is a simple way to have a fire if you don’t or can’t make one outside.
Take a pottery bowl and place a bit of Epsom salts in it.
Then take some rubbing alcohol.
How big a fire depends on the amount of alcohol and how much Epsom salts are put in.
In a safe place, light it.
It purifies the air too. And it gets rid of Negative energies.
