Do you feel that your children do not value water? Note that they are when they do one of the following:
1) Take long baths.
2) Don't turn off the tap properly.
3) Don't finish the water in their school containers.
4) Play water when they should be cleaning or watering the plants.
As soon as you see one of these signs indicating that they have taken water for granted, "shock and awe" them with this video.
You never know, they may be inspired to create their own version of "Watercone".
