12. If you had a 5-litre and a 3-litre bowl and access to water.
How would you measure exactly 4 liters?
Solution: Fill the 5-litre bowl
and overspill water to the 3-litre bowl, which you empty
afterwards. From the 5-litre bowl overspill the 2 remaining
liters to the 3-litre bowl. Refill the 5-litre bowl and fill in
the 3-litre bowl (with 1 liter), so there stay the 4 required
liters in the 5-litre bowl.
