An infinite lava pool is a visual effect in Minecraft that creates the illusion of an endless pool of lava. It is a popular decorative element for builds and can be used to create various effects, such as a fiery moat or a lava lamp. To make an infinite lava pool, you will need a bucket of lava, a water bucket, and a fire resistance potion.
To create the pool, dig a hole in the ground that is at least 2×2 blocks in size. Place the bucket of lava in the bottom of the hole and then use the water bucket to pour water around the edges of the lava. The water will create a barrier that will prevent the lava from flowing out of the hole. Finally, drink the fire resistance potion to protect yourself from the lava and then step into the pool. You will now be able to swim in the lava without taking any damage.
