Blob Tag
From Teampedia
Objectives
Get people moving around/energised
Group Size
Materials
Large open space, with set boundaries
Set Up
None
Directions
One person is designated as "it" and begins a game of tag. One someone is tagged they become "it" as well and must become part of the blob by linking arms with the other people that are it. The blob continues to grow until it has swallowed all the participants.
Possible Risks
If not careful the blob can become an unintentioned game of "crack the whip" with people at the end of the blob being flung off. Encourage the blob to move at a speed safe for all participants. This can be fun to watch, a well thought out blob can slowly separate other players and surround them.
