SPONGE RELAYS

1. Sponge Relay. At the front of each team will be a bucket with water and sponges beside it. At

 the back of each team will be a bucket with a line marked on the outside. On go, each member, 

 starting with the first one in line, will fill the sponge up and take it to the empty bucket and 

 squeeze it out. Rotate through the team members until the race is over. The winner is the team 

 who fills their bucket above the line first. The den leader may want to be the judge for this 

 event.

2. Sponge Toss. Line 3 empty buckets up side by side. Fill one more bucket with water and place

 sponges on the ground next to the bucket. Each scout takes a turn filling the sponge with water 

 and trying to throw it into one of the empty buckets. At the beginning announce how many 

 tries each scout will get, then let each have a turn. After the first rotation is through, if there is

 more time left for the game, let them continue.
