This is the first time this little boy has been able to drink water from a tap. Where do you think he got water from before this? Before this his mum or sister would walk for a long time to collect water in buckets from a river or a well. They might do this four times a day to makes sure the family has enough water for cooking, washing, drinking and watering the fields. Can you imagine how heavy a bucket of water is? Demonstrate this with a pile of books – add one at a time to the pile in a volunteer’s arms until they can’t bear the weight, then show them how heavy it actually is by holding the number of books equivalent to a bucket full of water.
