In Minecraft, an Ender Pearl is an item that can be thrown to teleport the player to the location where it lands. However, Ender Pearls will sink in water and become unretrievable. There are a few ways to make an Ender Pearl float on water, which can be useful for creating underwater bases or traps.
One way to make an Ender Pearl float on water is to use a Soul Sand block. When an Ender Pearl is thrown onto a Soul Sand block, it will bounce up and float on the surface of the water. Another way to make an Ender Pearl float on water is to use a Slime Block. When an Ender Pearl is thrown onto a Slime Block, it will stick to the block and float on the surface of the water.
