Build a hidden room in Minecraft

What can we use if we can't find sticky pistons or enough redstone for the hidden door?

If you can't get sticky pistons, use regular pistons with slime blocks or replace the piston door with a trapdoor/normal door hidden behind a camouflage outer wall and activate it with a lever or button, and if redstone dust is limited use repeaters, observers, or redstone torches to relay the signal to the pistons as you connect the trigger.

Why do my camouflage blocks clip or the door not open smoothly and how do I fix it?

If the pistons don't move the camouflage blocks cleanly, check each piston is facing the block you want moved, verify the redstone path from the lever/button reaches every piston, and adjust repeater delays or piston positions exactly as the instructions say until the door opens smoothly without clipping blocks.

How can I adapt this hidden room activity for different age groups?

For younger kids simplify by hiding a normal door or trapdoor and disguising the trigger with a painting or sign, while older kids can follow the full steps to place sticky pistons, connect redstone dust with repeaters for timing, add slime blocks or timed sequences, and ask a friend to try to find it.

What are some ways to extend or personalize the secret room after it's built?

Enhance the build by adding lighting and decorations inside, extra camouflage outside like matching blocks, plants or signs, hide the trigger more cleverly with a painting or trapdoor, add a redstone-activated chest or timed piston sequence for security, and share the finished creation on DIY.org.
