A crash course in changing the world.
I would have my event at a lake. All around the sides of this lake there would be stands for drinks and snacks. On the lake there would be heaps of those plastic bubbles that people can walk inside and lots of other water related activities ( using the water only from the lake ). entrance would be $5 per person and children under 5 free. All he money gained from this event would go towards getting fresh water pumps for those who need it.
