Measure Exactly 8 Liters of Water

Can you measure out exactly 8 L (8.5 qt) of water without an 8-L bucket?

Pails and pond

This puzzle is similar to the "Right Amount of Water" puzzle, which also was suggested by Interactive Mathematics Miscellany and Puzzles.

This time you have two empty pails. One has a capacity of 6 L (6.3 qt). The other can hold exactly 11 L (11.6 qt). Your task is to go to a pond and come back with exactly 8 L of water. How do you do it?
