science

Especially when the mistakes hurt. I was a kid in the '80s when this was practiced.

All the stuff I played on now has softfall padding under it, the giant slide has had a dirt bill built up under it so kids can't fall off the ladder; the high up stuff was removed

Me and my friends would climb to the high cubby house and feel very daring. I think it was 10m up. There were three of them with the lowest being maybe 5m up - parents couldn't reach it.

We were not daring enough to try the Tarzan swing - a circle of tiered seats rising in the arc of the rope that hung above the centre, so you could take the rope to any point on the tiers and swing from there. I think there was a knot in the bottom of the rope, but the older boys swung with their feet loose, hanging on Tarzan style. That was the only one they pulled out during the '80s. Everything else survived to the late '90s
