Explosion-powered low-tech elevator

I am making a world where people live without access to many raw materials, including metals and wood. Among other things they harvest their own dead for a paper analogue.

Another thing that is harvestable from corpses is gas, so I have been thinking. In our own world, people sit on airbags and activate them for fun, with often spectacular results.

Could people do something similar to exploding airbags with natural gas, contained in leather bags?

And if so, could they place a slab of ice on it and use it as a plataform, to elevate people or cargo to a higher position (supposing there is someone or something to catch them in the apex of the leap)?
