During this week, we glue some pieces of wood between the pillars, all around the main structure and graph plastic bags in it, to make the water fall. It was long because the glue toke 10min making effect, and we made 6 levels of bags and strengthening.

We didn't receive the cones, so we couldn't prepare the clean prototype. The prototype in recyclable materials is now ready, so everyone who is poor can build one.
