Works with Claude, ChatGPT, Gemini, or your own local model: paste this prompt and your AI will co-facilitate this exercise with you.

Help me prepare and run the exercise below. First ask for my participant count, time, setting, access needs and intended result. Check these against the stated limits. Use the supplied rules and materials. Explain any proposed changes before using them, and label them as adaptations. Do not invent source claims or require personal disclosure. Give me one step at a time when I say start. I manage the people, physical activity and clock; do not claim to observe the room. Ask me what happened before choosing a next step.

# Cross the Line

Partners stand facing each other across a floor line and spend thirty seconds trying to verbally persuade each other to step across. The room then compares competitive and collaborative negotiation tactics.

**Time:** 10 minutes. UWT 10-minute structure expanding TrainerBubble's 30-second exercise to include paired reflection and whole-room debriefing
**People:** 4 to 24. Pairs facing each other across a line, with an observer role for an odd participant

## Choose this exercise

**Purpose:** Compare verbal influence tactics and identify mutual-gain solutions under brief time pressure.
**Use it when:** Use at the start of a negotiation, sales, or conflict-resolution session to surface default negotiation instincts.
**Skip it when:** Skip if the group includes people experiencing mobility limitations or where physical proximity across a floor line causes discomfort; use a verbal tabletop alternative instead.

## Materials and tools

- 1 roll of masking tape, painter tape, or floor cord
- 1 digital countdown timer or stopwatch

## Before participants arrive

1. Lay a straight line of tape on the floor at least 2 meters long, or several shorter parallel lines to accommodate pairs without crowding.

## Say this to open

Stand facing your partner across the tape line, about an arm's length apart. Please keep your hands at your sides. Do not touch, pull, or physically force your partner. When I say go, you have exactly thirty seconds to persuade your partner to cross over to your side of the line. Begin.

## How to run it

### 1. Form pairs and state rules (2 minutes)

Pair participants and place each pair facing one another across the floor line. Deliver the opening script. State the constraint clearly: words only, strictly no physical contact. If there is an odd number, assign one person as a neutral timekeeper and observer.

### 2. Run 30-second persuasion attempt (1 minutes)

Start the timer and call 'Go'. Allow pairs exactly 30 seconds to persuade one another. Call 'Halt' at 30 seconds. Ask participants to freeze in place so the room can observe who crossed, who stayed, or if both swapped sides.

### 3. Compare tactics in pairs (2 minutes)

Have partners spend two minutes comparing notes on the offers made, whether threats, trades, or appeals were attempted, and why they complied or resisted.

### 4. Facilitate room debrief (5 minutes)

Gather the full room. Ask 3 or 4 pairs to share the tactics used. Highlight zero-sum assumptions versus mutual-benefit agreements, such as swapping places so both achieve the objective.


## Debrief questions

- What specific words or offers persuaded you to step across, or what made you dig in?
- Did anyone consider that both partners could cross over and both win?
- How does our default reaction under time pressure limit the solutions we see?

**Finished output:** A room-level catalog of verbal negotiation tactics grouped into coercion, concession, and mutual trades.

## Remote

Assign participants to breakout pairs for 30 seconds. Person A tries to convince Person B to change their video background or type a specific phrase in chat, while Person B does the same to Person A. Reconvene in the main room to debrief negotiation tactics.

## Hybrid

Pair in-person participants with in-person partners along the floor line. Pair remote participants with remote partners in breakout rooms using the video background or chat variation. Combine both cohorts in the shared room for the plenary debrief.

## Access and participation choices

- Participants may complete the exercise seated across a table with a center marker or pen representing the line.
- Any participant may decline active role-playing and act as an observer recording the influence tactics used.

## If the session gets stuck

**Participants start grabbing hands or pulling each other across the line.**

Intervene immediately, stop the round, and remind the room that physical contact is not permitted and only verbal persuasion counts.

**Neither partner speaks because both assume it is an immovable standoff.**

Call time at 30 seconds and use that standoff as a direct debrief example of how competitive framing causes instant deadlock.


## Terms used here

- Mutual-gain solution: An agreement where both parties fulfill their objectives rather than one party winning at the expense of the other.

## Sources and adaptation

Observed in TrainerBubble training materials under the title 'Cross the Line : Free Energiser'. Original authorship is not specified in supplied sources.

Retained the core mechanic from TrainerBubble: two people facing across a floor line with 30 seconds to persuade the other to cross, ending with the collaborative swap insight. UWT added explicit safety rules prohibiting physical contact, a timing breakdown totaling 10 minutes, observer accommodation for odd numbers, and remote and hybrid adaptations.
