Blob Tag

Choose this exercise

Purpose: Coordinate collective movement and navigation under changing physical constraints.

Use it when: Use in an open indoor gymnasium or level outdoor field when a group needs an active physical game emphasizing cooperative movement.

Skip it when: Skip in small meeting rooms, carpeted office spaces, or settings where fast physical contact and running present safety or accessibility barriers.

Group arrangement: Initial pairs transitioning into an expanding chain.

Timing: UWT suggested allocation based on typical 5 to 15 minute running tag formats.

Materials and tools

• 4 boundary cones or markers
• 24 short hand-towels or ropes (up to one per participant, for optional non-contact links)

Before participants arrive

1. Mark a clear, flat boundary roughly 20 meters by 20 meters using cones.
2. Check the floor surface for slip or trip hazards.
3. Stage towels or short ropes along the boundary for participants who prefer not to hold hands directly.

Say this to open

We are going to play Blob Tag. Partner up with one person. You will move together while staying connected, either by holding hands, linking elbows, or each holding one end of a short towel. One pair starts as the Blob. When the Blob tags another pair with a free hand, that pair separates and attaches to the outer ends of the Blob. If the chain breaks, the Blob cannot tag anyone until you reconnect. You can release your grip at any time if you feel unsafe or uncomfortable.

How to run it

1. Form pairs and designate the initial blob 3 minutes

   Ask participants to form pairs. If there is an odd number, assign one participant to act as boundary judge and safety referee. Have each pair choose their connection method (holding hands, linking forearms, or each holding a short towel). Choose one volunteer pair to start as the initial Blob. All other pairs spread out across the marked play area.

2. Run the chase and chain expansion 8 minutes

   Signal the start. The starting pair chases other pairs. Only runners on the outer ends of the chain may tag using their free outside hand. When tagged, the fleeing pair splits: one attaches to the left end and one attaches to the right end. If the chain breaks, the Blob cannot tag until reconnected. If a fleeing pair disconnects, they must halt and reconnect before fleeing again. Play until one fleeing pair remains or time expires.

3. Cool down and reform group 2 minutes

   Call time. Invite everyone to walk to the center of the play area, catch their breath, return any towels or ropes, and assemble in a circle.

4. Debrief coordination 2 minutes

   Facilitate a brief whole-room reflection. Take 2 to 3 voluntary observations on how movement communication shifted as the chain grew.

Debrief questions

• What strategies helped your pair stay connected while moving quickly?
• How did communication change once the chain grew longer than four people?
• What made turning difficult for the larger chain, and how did you adjust?

Finished output: Completion of a physical tag round resulting in a single connected chain or identification of the final remaining pair.

Remote

This active running tag activity requires shared physical space and cannot be run online as designed. For a remote coordination alternative that practices rapid cooperative adjustments, run a virtual group countdown game where participants coordinate unmuted turn-taking numbers without overlapping.

Hybrid

Hybrid delivery is not possible. Remote participants cannot share the physical running space safely.

Access and participation choices

• Offer short towels or grab ropes so participants can connect without direct skin contact.
• Allow walking-only rules if sprinting presents an injury risk for the group.
• Participants may step out without explanation or take an active role as boundary monitor, safety judge, or scorekeeper.

If the session gets stuck

The chain snaps repeatedly because people run in opposite directions.

Pause play and instruct the chain to assign a verbal direction caller at one end before resuming.

A fleeing pair runs outside the marked boundary lines.

Remind runners that stepping out of bounds counts as being tagged, and direct them to attach to the ends of the chain.
