This guide will tell you how to get Powder Snow in Minecraft MCPE, Java, And Bedrock Edition 1.17. You just have to follow the simple steps below to get it.
First of all, you must have a cauldron and a bucket and then enter a snowy bio that can be a frozen ocean. After that, you need to put a cauldron at any point in the snowy place. The cauldron should be under the sky and ensure that nothing is blocking the skylight from reaching the cauldron. Then you have to wait for some time for rain and once the rain or snow starts, your cauldron will fill with it.
After this, you have to take your bucket and then right-click on the cauldron. Now you will get the powdered snow.
