Be invited to the following experiment:




Kelso would have been better advised to describe it as ballistics - a pretty well understood branch of science, as it should be considering all the work various war efforts have put into its study. Do the calculations on your phone's calculator... Well maybe it'd be easier with some ballistics software but it ain't really that hard, surely you remember calculating trajectories at high school.

Unless there were fairly strong winds the only real variable would be the friction between the "projectile" and the slide. Get this consistent so the launch velocity (read muzzle velocity) is always the same and the rest would fall into place fairly easily.

I reckon your billiard table analogy doesn't hold up as a comparison because there are no bounces to take into consideration.

All that said, the video is certainly a fake as demonstrated in another post. Possible? YES. Would I do it? No, but if I did I'd really want to work up to it, and that pool would need to be set up a LOT better, actually I think I'd prefer a platform of stacked empty cardboard boxes covered with a tarpaulin - I like soft landings.

You're only paranoid if you're wrong!
