The Guides are in two files. Have them number by 2. The number two's take two steps aside: thus you get four files.
Each team gets two balls. The balls criss-cross, going from the 1st Guide of one file to the second Guide on the other file, then to the third Guide of the first file etc.
The first team to finish wins.
Use water balls outside, to make this even more fun.
