Cold winter is a sort of energy for building a structure
Even without either adhesive or screw, it would be a frame or structure for a while because of below -2C
I borrowed a old manila rope from Michelle (Yale-China Association), then soaked it in the cold water. After that, I went outside and hung it on the branch. 2 hours later, if the outdoor temperature kept below -4C, the rope will be frozen and become a form of frame. It is unstable because of the fragile ice, however, if applying a better structure design on it, it can hold better.
