Comets

Choose this exercise

Purpose: Coordinate simultaneous catching and throwing timing between partners in an open physical space.

Use it when: Use during an outdoor energizer, physical warm-up, or movement break when participants need a fast-paced physical challenge.

Skip it when: Skip in confined indoor rooms, areas near breakables or road traffic, or when the group seeks quiet, non-physical reflection.

Group arrangement: Solo practice moving into pairs; an odd participant forms a trio or acts as timekeeper/coach

Timing: Playmeo source specifies 5 to 10 minutes of active play; UWT allocates 15 minutes to include setup safety briefing, pairing, and a short debrief.

Materials and tools

• 1 comet per participant (1 tennis ball inserted into the toe of 1 knee-high stocking or nylon tube sock)
• 4 spare comets (tennis balls in knee-high stockings) in case of rips
• 1 whistle or loud horn for safety stops

Before participants arrive

1. Substantial setup needed before the clock starts: construct one comet per participant by placing a tennis ball in the toe of a knee-high stocking and knotting the opening.
2. Inspect an outdoor, open lawn or gymnasium clear of obstacles, low-hanging wires, and non-participants.

Say this to open

Today we are playing Comets. Each person gets a comet made of a tennis ball inside a stocking tail. You will swing it by the tail or ball to launch it high, and catch it by either the tail or the ball. First you will practice on your own. Then you will pair up to exchange comets in mid-air at the same time. If at any point I blow the whistle, freeze where you are.

How to run it

1. Introduce and demonstrate 3 minutes

   Hand out one comet to each participant. Bring up one volunteer. Demonstrate how to hold the tail to swing and launch the comet into the air, and how to catch it either by the tail or the ball. Demonstrate a gentle simultaneous two-way toss with the volunteer. Point out safety boundaries and state the stop signal.

2. Solo launch and catch practice 3 minutes

   Direct participants to spread out across the space with at least 3 meters of clearance around each person. Direct everyone to practice launching their comet upward and catching it themselves. Prompt them to try launching from the tail, launching from the ball, and catching by the streamer tail. Stop play after 3 minutes.

3. Partner simultaneous toss 6 minutes

   Have participants pair up and stand facing each other 3 to 4 meters apart. If there is an odd number of participants, place one group in a triangle of three, or offer the extra participant the role of distance coach. On a count of three, partners launch their comets simultaneously across to each other and attempt to catch the incoming comet. After three clean catches in a row, both partners take two steps backward to increase the throwing distance. Continue until the time expires.

4. Group debrief 3 minutes

   Gather participants in a circle. Call for two or three brief observations on what adjustments helped partners catch simultaneously without collisions.

Debrief questions

• What adjustment in your launch angle or release timing made it easier for your partner to catch?
• How did you communicate with your partner to avoid mid-air collisions?

Finished output: Pairs complete simultaneous comet catches and establish their maximum functional distance.

Remote

Comets is an outdoor physical throwing activity and cannot be delivered as an equivalent online game. If running a remote session, replace this activity with a digital reflex drill such as Virtual Quick Draw, where pairs react to verbal prompts in chat.

Hybrid

Hybrid delivery is not recommended. If attempted, in-person participants run the physical activity in pairs outside, while remote participants pair up in a breakout room to run a virtual timing challenge (such as clapping simultaneously on an unspoken visual beat).

Access and participation choices

• Participants can choose to underhand toss the ball directly without using the centrifugal tail swing if shoulder mobility is limited.
• Participants may pass on catching and instead act as distance coaches or scorekeepers without providing personal reasons.

If the session gets stuck

Comets collide in mid-air and fall to the ground every time.

Instruct pairs to agree on trajectories before throwing: one partner throws high with an arc, while the partner throws on a flatter, lower trajectory.

Participants throw with too much force, causing near misses or safety concerns.

Pause the group and enforce a rule that every throw must have an upward arc higher than head height before descending.
