For a while now, I've been very into grappling guns and the ability to swing around buildings, etc. Specifically been very interested in the odm gear present in the show "Attack on Titan". It's a device that has two launchers in each side of the hip that fire grappling hooks with a cable and attach them to the wall, to then rapidly reel over the cable to allow the user to swing around. Something like this.
The question relies in how of if it is posible to change the design of the grappling hook to instead of breaking through stone or brick and attatching, could just stick to it with the geckskin.
In this article it says that 16 square inches of geckskin (an artificial material inspired by the skin of gecko feet) can handle up to 700 pounds when properly attached to glass, so I think it can support a 170 pounds human reeling the cord at maybe 2Gs of acceleration (making the total weight to around 340 pounds) when sticking it to a brick or rock.
The usage of it doesn't have to be as flashy as in the clip but a bit more realistic. Something similar as how spider-man uses his webs.
If someone could give me a hand on ways to design it would be very useful :)).
Edit: Sorry for not making clear the question, I've changed it a bit and maybe now it is more clear. Thank you.
