The reactor cycle would end after 45 seconds, damaging the reactor`s structure and changing the world to night. The reactor was replaced with a 3⃗3⃗3 box of obsidian containing the core, which adopted a darker, blue-black texture to indicate that the reaction has ended. If the player built a new reactor around the burnt out core, the netherrack spire would generate, although the rest of the reaction would not take place.
The reactor could be activated in Creative Pixel art and other creations made in Creative mode. "Sandbox" redirects here. For a place to test edits to this wiki, see Minecraft Wiki:Sandbox. Creative mode is one of the main game modes in Minecraft.

Trivia
- The spire was composed of over 25 stacks worth of netherrack.
- Excluding the core, any part of the reactor could be mined after activation and it would still function. This way, the player could recycle the expensive gold blocks. It was possible to recover all 4 blocks provided the player worked quickly.
- Because the spire could not replace blocks past the world border, when the reactor was activated near the edge of old worlds the player would be able to see the time set to night.
- If the nether reactor core Nether Reactor Core Type Solid Block Requirements None Physics No Transparency No Luminance Yes Blast resistance 30 Hardness ? Tool Renewable No Stackable Yes (64) Flammable No First appearances See History Drops Diamond (3) Iron
was mined out while the nether reactor is active, the glowing obsidian would not turn into obsidian after the reactor deactivates. This also caused the reactor to stop spawning items and zombie pigmen.

If the structure was incorrect, attempting to activate the reactor resulted in the client message "Not the correct pattern!".
Conditions
- That all players were in range of the reactor`s effects on activation.
- That the reactor was built within the valid range (Y: 4-96).
- That the player who activated the reactor was standing level with the structure.
