Hi I am giving a talk on forces in climbing as part of science week at a local primary school to years 5&6 (10,11 ish).
I've got a rough plan (very happy to get any ideas) of what to talk about and some live demos of friction etc but I am looking for a video of a big whipper to kick off. Something that's clear, without swearing, a short clip (i can probably extract one), on bolts, I've been looking on Youtube but nothing grabs me yet
any other suggestions very welcome
