We got to use an old Maori hand drill. You had to carefully
twist the strings and hold them between you thumb and finger, then gently but
quickly pull them in and out, while pushing downward. It was tricky to start
with but easy once you got the hang of it.
Another stand out activity was the Leonardo Da Vinci Bridge.
You had to carefully construct the bridge which is made only of sticks, no
nails or anything! It was strong enough that we could walk over it.
