When looking up tutorials I found one on making a campfire, you use pistons, lava, water, a bed and 6 or more armor stands and fence posts.  When you place lava on one corner and water on the other to prevent it from burning the armor stand will perpetually burn and look like a camp fire. In bedrock there is no fire, it just flashes red and then no matter what it will eventually disappear.  Here is a link to a video that shows how to make one.
