You are again building a tin foil hat. No? The instructions to build it in Deponia are here. Forget, for now, that you will be building it again here in Elysium.
Fine, good. So, go ahead. The recipe is the same.
Some tinfoil and a straw.
In the council of elders floor (pink note in the elevator) there is this elder laying in his hammock. He has some tin.
Exchange his reading lamp with the heating lamp you can find from the chill-out zone. It is heating the chickens.
.. and red, yes. Also he dropped his tin thingy and the grass became... straws.
So, pick up the tin and the straws and combine them in your inventory. Ta-dah! A tin foil hat.
