If you had an infinite supply of water and a 5-liter and 3-liter bucket, how would you measure exactly 4 liters? The buckets do not have any intermediate markings.

Fill the 5-liter bowl. Then fill the 3-liter bowl from the 5-liter bowl. You will now have 2 liters left in the 5 liter bowl.

Empty the 3-liter bowl, and then transfer the 2 liters from the 5-liter bowl into it.

Now fill the 5-liter bowl again, then pour water carefully from the 5-liter bowl into the 3-liter bowl until it is full - exactly one more liter.

The 5-liter bowl now has exactly 4 liters.
