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.

# The Elusive Shadow

Participants head outside on a sunny day and try to touch the head of their own shadow with their own physical hand. The impossible physical puzzle prompts quick physical experimentation, laughter, and a brief discussion on perspective.

**Time:** 5 minutes. UWT suggested duration based on source quick-energizer classification
**People:** 4 to 24. Individual movement in a shared open space

## Choose this exercise

**Purpose:** Provide a brief outdoor physical reset that challenges participants to test assumptions about an impossible task.
**Use it when:** Use during an outdoor break or transition when an in-person group needs a light, physical shift in attention and energy on a bright day.
**Skip it when:** Skip on overcast or rainy days, indoors without direct focused light, or when any participant cannot comfortably move outdoors on uneven ground.

## Materials and tools

- No special materials.

## Before participants arrive

1. Locate an open, flat outdoor area with direct sunlight and clear ground shadows.

## Say this to open

We are heading outside for a two-minute puzzle. Once you find a spot in the sun, your task is simple: touch the head of your own shadow using your own physical hand. Move at your own pace and see what happens.

## How to run it

### 1. Set the challenge (1 minutes)

Lead the group outside to an open, sunny area. State the rule clearly: each person must attempt to touch the head of their own shadow using their own hand. Answer clarifying questions without revealing whether it is physically possible.

### 2. Attempt the tag (2 minutes)

Say 'Go.' Let participants experiment individually with reaching, bending, jumping, or moving toward their shadows. Stop the round after two minutes or once people recognize the physical paradox.

### 3. Share creative workarounds (1 minutes)

Invite anyone who found a clever workaround to demonstrate it. For example, leaning against a wall or using another surface to fold the shadow.

### 4. Brief debrief (1 minutes)

Ask one debrief question to transition back inside or to the next agenda item. Take two brief comments from volunteers.


## Debrief questions

- What assumptions did you notice yourself making as soon as you tried to catch your shadow?
- What strategies did you try once you realized the basic reach would never work?

**Finished output:** Completion of a physical movement puzzle by all present participants who choose to try.

## Remote

This physical energizer requires direct outdoor sunlight and cannot run as an equivalent remote activity. For an online group, run a different quick visual reset instead, such as having participants touch their own camera frame on screen.

## Hybrid

Hybrid delivery is not recommended. If attempted, remote participants step outside into direct sunlight with mobile devices, or try to tag their room shadow cast by an indoor lamp, while in-person participants work outside.

## Access and participation choices

- Participants may observe, photograph, or partner with someone else rather than running or bending down.
- Anyone may opt out by simply standing in the shade without explanation.

## If the session gets stuck

**Overcast weather or poor lighting removes all visible shadows.**

Postpone the activity for a sunny day or swap to a standard stretch break.

**Participants bump into each other while chasing shadows.**

Ask everyone to spread out with at least two arm-lengths of buffer space before starting.
