After a brief video of the discoveries made in the Sterkfontein caves, they climbed into a succession round boats, each carrying four people. As each boat was loaded it launched onto an underground river and carried its passengers through waterfalls (which thankfully turned off just before each boat went under them), ice caves, visual fire effects and wind, all depicting the early years of earth’s development. I suspect that the teachers were more nervous than the children.
After a wobbly disembarkation, everybody tested their skills in one way or another, learning more about evolution and its impact on the earth.
A short bus ride followed, and helmets were donned for the Sterkfontein caves, and finally the garden of statues depicting famous South African people.
