Choose slime when the block should conduct redstone or its bouncing effect is useful. Both can move adjacent movable blocks, but the details of redstone and entity behavior vary between Java and Bedrock.
How honey and slime blocks differ
| Build requirement | Honey block | Slime block |
|---|---|---|
| Move adjacent movable blocks with a piston | Yes | Yes |
| Stick to the other block type | No | No |
| Carry entities standing on top when moved | Yes | Slime bounces entities away |
| Conduct redstone | No | Yes |
Both blocks can form the sticky part of piston mechanisms, including flying machines. A piston can move up to 12 blocks, so count the entire assembly—not just its honey or slime blocks—when planning a design. See the flying-machine reference and the honey block reference for these mechanics.
When honey is the better choice
Carry a rider on a moving platform
A piston-moved honey block carries entities standing on its top surface. That makes it useful for a platform intended to transport a player or mob instead of bouncing them away. Contact behavior on other faces is edition-dependent: the honey-block reference reports that Java does not move entities touching the side or bottom of piston-moved honey, while Bedrock moves entities touching the side.
Keep neighboring assemblies independent
Honey does not stick to slime, and slime does not stick to honey. Builders can use the boundary between them to keep adjacent piston assemblies from being dragged together. Mojang announced this rule for Java Edition in its 19W42A snapshot announcement, which states: “Honey Blocks and Slime Blocks no longer stick together”.

Avoid signal transmission through the sticky block
Honey is non-conductive, so it can help prevent unwanted redstone signal transmission through a block in a mechanism. This can be useful when a design needs moving parts without the sticky block also acting as part of the signal path.
When slime is the better choice
Use the block as part of a redstone signal path
Slime conducts redstone; honey does not. If the sticky block needs to carry a signal as part of the layout, slime is the appropriate choice.
Use its bouncing behavior
Slime blocks bounce entities rather than carrying them along on top in the way honey does. That behavior suits builds designed around bouncing, but it is a poor fit if a rider must stay aboard a moving platform.
Do Java and Bedrock behave the same?
No. Minecraft’s flying-machine reference documents Java and Bedrock separately because mechanics vary, and Microsoft notes that redstone differs between the editions. In particular, the entity-contact behavior of piston-moved honey differs between Java and Bedrock as described above. A design that depends on precise entity movement or circuit behavior should be checked in the edition and version where it will be used. See Microsoft’s Java and Bedrock differences guide for the cross-edition caveat.
