It fails at the joins.

A whole-studio chain reaction where every team's section has to hand off to the next. Individually easy, collectively brutal, and it breaks exactly where the Lip Dub will break - at the handoffs. Also six seconds of very good Exhibition footage.

The day's purpose

By 2:40 today the studio has felt, in about four seconds, that the handoff belongs to two teams and neither can fix it alone.

// success criteria · 01

Neighbors talked first

The first five minutes went to negotiating joins, not building middles. That order is the whole lesson.

// success criteria · 02

Instructions got tested

Each team watched someone try to follow their writing. The failures were more useful than the successes.

// success criteria · 03

Repairs were owned, not crowdsourced

When a join failed, the two teams who owned it fixed it - without the guide and without the room shouting.

// artifacts in play today

Work It Out (Wk 2) gets named at launch as the tool for today's neighbor negotiations. Boat teams (Wk 3) are reused deliberately - they already know how to disagree with each other. The shared-materials rule is lifted straight from Week 2's tower challenge, and someone will notice.

Morning Launch - the handoff

Talking points, not a script. Hit these in your own words - the studio can tell the difference, and the ones that land are the ones you actually mean.

The opener (3 min):

"Yesterday I said this only works if everyone hits their bit. Today we're going to build something where that's literally true, and where you can watch it fail in about four seconds."

The core (12 min):

Introduce the chain reaction: a machine made of sections, one per team, where each team's section has to hand off to the next team's. A marble, a domino, a rolling can - something has to leave your section and arrive in theirs.

Then the actual lesson, which is not about marbles:

  • "The middle of your section is easy. The join is hard. Same as the boats - cardboard doesn't fail in the middle, it fails at the seams."
  • "And the join isn't yours. It belongs to you and the team next to you. Neither of you can fix it alone."
  • "That's exactly what the Lip Dub is. Your bit is easy. The moment where you hand off to the next person is where it breaks."

Then reach back to Week 2 explicitly: "You have a tool for negotiating with people you disagree with. It's on that wall. I'd use it today."

The close (5 min):

"Nominations close at snack. Vote is tomorrow at Town Hall."

Quest - The route, before the song

// purpose

The song isn't chosen until tomorrow, which makes today look like a gap. It isn't - the route doesn't depend on the song. Walking it now buys the studio an extra rehearsal day it would otherwise never get, and the route is the thing W5D2's blocking rehearsal says the whole film breaks on. A studio that has walked it four times by Friday shoots better than one that meets it on the Tuesday.

1 - Song advocacy (15 min):

  1. Read the nominations so far. Any that fail the criteria come off now, out loud, with the reason - "that one's five and a half minutes" - so the standard stays visible rather than arbitrary.
  2. Every nominator gets sixty seconds to make a case. Not "it's a good song" - why is it a good song for a studio in a corridor with one camera?
  3. Anyone may nominate up to the end of this block. Then the box closes.

2 - Scout the route (20 min) - the real work of the day:

  1. Walk the building as a studio and decide where this thing physically happens. Corridors, doors, corners, stairs if you're brave.
  2. One learner walks it backwards holding nothing, at the speed a camera operator would actually move. Everyone else watches. That's the route - not the one that looks good on paper, the one a human can walk backwards.
  3. Mark the turns. Identify every pinch point, every door that has to be open, every place two people would collide.
  4. Write down what has to be true: doors unlocked, other studios warned, nothing on the floor.

3 - First walk-through, no song (10 min):

Everyone spreads along the route in roughly the places they think they'll be. Walk it once, end to end, at half speed, in silence. It will be shapeless and that's fine - the point is that the whole studio has now physically been through it once.

4 - Close (5 min): one question - "Where is this going to go wrong?" Write the answers up. Every one of them is a thing Thursday and Friday get to fix.

Carry forward: the route map goes on the wall and gets marked up all week. Floor tape can wait until Week 5, but the map shouldn't.

// if you finish early or need a change of gear

The Portrait Wall and Chain Reaction are parked on the Week 4 overview as Backup Activities, written out in full. They are genuinely good and they're there when the studio needs a break from the same song - but they don't get to eat a Quest block that rehearsal needs.

Studio Maintenance

Chain reaction materials go back to shared storage rather than to teams - it'll be rebuilt in some form later. Floor markings come up.

Character Callouts

The callouts today are all at the joins: who went and talked to the neighboring team first, who fixed a join that wasn't their fault, who let go of a section design that didn't fit the machine.

For learners ready to lead

  • The most valuable job today is a learner who walks the whole machine and manages the joins across all teams. That's a systems role and it barely exists anywhere else - offer it.
  • Ask a strong writer to test their instructions on the youngest-reading learner in the room rather than on a peer.
  • A team that finishes early should be sent to their neighbor, not to a random team. The join is the shared property.

For learners who need more scaffolding

  • "Build a section" is open-ended. Offer three worked examples on a card: a ramp, a domino line, a lever.
  • Writing instructions is easier with a numbered template and a hard limit of six steps.
  • Give a two-minute warning before each run attempt - the stop-start rhythm is jarring otherwise.

For specific learner needs

  • Repeated public failure is hard for learners who take it personally. Say clearly and in advance that the machine failing is the expected outcome and that not completing it is fine.
  • Marbles, noise and sudden collapses are a sensory load. The camera operator and the instruction-tester roles both sit slightly outside the chaos.
  • Watch for a learner being blamed for a failed join. Step in immediately - the join is never one person's.

For the guide

  • Only ask about joins. If you start solving sections you'll spend the afternoon engineering and they'll spend it watching.
  • Screen every nominated song tonight - lyrics and licensing both. If one of them can't be used for the way we're planning to share the film, it comes off the ballot before the vote, quietly, and you tell that learner privately why. A public veto after the vote is corrosive, and licensing is the one that gets discovered too late.
  • Note which teams reused Work It Out without being told. That's Week 2 paying off and it's worth a callout tomorrow.

Parent communication today

Talking points for this week's email. Drop these into an AI assistant along with two or three live notes from your actual week - a name, a moment, something that surprised you - and it'll give you a draft in your own voice. The specifics are what make it land; the structure below is just the scaffolding.

The draft underneath is an example of the shape and the tone, not a template to send as-is. A parent who gets the same email as every other parent can tell.

Subject: Walking the route before we have a song

Hi families,

An odd-sounding afternoon: we walked the route for a music video we haven't chosen a song for yet. That's deliberate. The route doesn't depend on the song, and walking it now buys the studio an extra rehearsal day it would otherwise never get.

One learner walked the whole thing backwards at the speed a camera operator actually moves, while everyone else watched - because the route that works on paper and the route a human can walk backwards are two different routes. They marked every corner, every door that has to be open, and every place two people would collide. Then the whole studio walked it once in silence, which was shapeless and useful.

Earlier, everyone who nominated a song got sixty seconds to make a case for it - not "it's a good song," but why it's a good song for a studio in a corridor with one camera. The vote is tomorrow, and it's final once it's taken.

Worth knowing the shape of it: we film on Thursday of next week. Early on purpose - if something goes wrong we want a week to fix it, not a night.
