Assuming that each tilt represents a step, the following method is the fastest possible.
1. First fill the 5 liter bucket full.
2. Then pour 3 liters into the 3 liter bucket. There are then 2 liters in the 5 liter bucket.
3. Now tip the water contents of the 3-liter bucket back into the water source.
4. Now tip the 2 liters in the 5 liter bucket into the 3 liter bucket. The 5 liter bucket is now empty and the 3 liter bucket contains 2 liters.
5. If you now refill the 5 liter bucket with the water source, you will have 3 liters in the 5 liter bucket.
6. The last step is to fill the 3 liter bucket with the 5 liter bucket. Since there are 2 liters in the 3-liter bucket, there are now 4 liters left in the 5-liter bucket.

Another, also efficient method:
1. First fill the 3 liter bucket.
2. Then you tip the contents into the 5 liter bucket. There are then 3 liters in the 5 liter bucket.
3. Now pour another 3 liters into the empty 3-liter bucket.
4. Then fill the 5 liter bucket with it. There is then 1 liter in the 3 liter bucket.
5. Now tip the water contents in the 5-liter bucket back into the water source
6. Now tip one liter of the 3-liter bucket into the 5-liter bucket.
7. Now fill the 3-liter bucket again.
8. The contents are then poured into the 5 liter bucket, which already contains one liter. There are now 4 liters in the 5 liter bucket.<end_of_turn><eos>
