Build a forbidden button with a chain reaction and a snitch bulb.
One big red button. One sign: DO NOT PRESS. And a secret bulb that snitches on anyone who does.
- New skill Building a delayed chain reaction
- Level 6 · Inventor's Lab
- Difficulty Intermediate
- Mode Creative
- Time 40–60 min
- Ages 13+
What you’ll build
Build one big red button with a DO NOT PRESS sign and wire it to a chain of chaos: alarms, lamps, then fireworks shooting through the roof. A hidden copper bulb secretly remembers every press, so you can catch anyone who couldn't resist.
Finish line: Your DO NOT PRESS button sets off a three-stage chain reaction, and the snitch bulb tells you who pressed it.
Bonus challenge: Add a second bulb that flips only when the first one lights up (a comparator can read a lit bulb). That's a 2-bulb counter: how many states?
You’ll need
- A button
- Repeaters
- Dispensers
- Firework rockets
- Note block
- Copper bulb
You choose
- My warning sign says
- The chain reaction's grand finale
- My top suspect
Stuck?
- Wax the copper bulb with honeycomb, or it ages over time and glows dimmer.
- Fireworks hitting the ceiling? Aim the dispensers up through an open hole in the roof.
- The bulb flips on every press, so an even number of presses looks like no presses at all.
