Duck tape (or do whatever you can) to make 4 ropes fastened to opposite sides of the pool (either the width or length of the pool). It's best to tie the ropes to something very strong on both sides of the pool (duct tape might work, but you'll probably need lots of layers).
You'll have 2 ropes close together per team so in total you'll have 4 ropes. On the mark of "GO" the first team member of each team walks on the ropes (which are on the surface of the water) to the other side.
The first team with all members to the other side wins!!
