About this project
What does Ironrot add?
They pour it on the ground, step into it — FLY into the air and die 😂
They get kicked to the main menu
Prank successful
✅ The real truth (for you, not for your friend)
Ironrot has ALL THREE fluids:
| Fluid | Real effect | Real recipe |
|---|---|---|
| Iron Water | Suffocation in a block | Smelt Iron Ingot |
| Dirt Water | Launch + fall damage | Smelt Grass Block |
| Sculk Water | Lightning strike | Smelt any Sculk block |
After dying to any fluid → kicked to main menu.
📋 Fake recipes (for the prank — show these to your friend)
| What your friend thinks | What actually happens |
|---|---|
| "Dirt Water doesn't exist" | They smelt Grass Block → get Dirt Water 😂 |
| "Sculk Water doesn't exist" | They smelt Sculk → get Sculk Water 😂 |
| "Nothing will happen" | They die and get kicked |
