Total darkness setup tip

after making multiple diferent setups to reach total darkness in a room i found a way wich you can easily set it up and take off if needed.

this is a way to prevent light to enter trough a glass window, wich in my case was always the biggest light source.

you only need to stick aluminum foil in the glass using water, its really easy to do and does not leave any residues on the surface wich happened to me when trying to use tape.

i cut the foil in rectangular shapes and wet the window using a spray bottle of water, and layer them until covering the whole surface with the reflective side directed outside, you can shine a light on the other side to see if you did a good job, but it doesnt need to be actually completely dark, in fact, advanced practitioners suggest using light slits to locate yourself when doing tensegrity.

the most important part is going in there and putting in the work!

and for not going through a whole roll of it in a week, just fold the pieces after taking them off and reutilize in the next night.

hope this helps someones practice!
