What you’ll build

Build a giant iron-and-glass hall with an arched glass roof and a stand for every invention from this era. Lay a timeline path through it, give a tour where your visitor guesses each year, then build a glitching time machine pad at the far end.

Finish line: Your glass hall shows every invention on a timeline path, the tour is scored and the time machine is set for the Future.

Bonus challenge: Add a mystery door at the end of the timeline with a sign: what invention comes next? Let your visitor guess, then check in the next era.

You’ll need

  • Iron blocks
  • Glass
  • Signs
  • Building blocks for models
  • A family member as visitor

You choose

  • My exhibition's name
  • The invention on the centre stand
  • My bet: visitor's score out of 8

Stuck?

  • Roof sagging? Build the iron arches first, then fill the gaps with glass.
  • Timeline path spacing tricky? At 1 block = 5 years, divide each gap in years by 5.
  • Visitor guessing wildly? Give one clue at each stand before they guess.
