Now you need to pour the solution into a saucepan, put it on the fire. When the water warms up and all the salt dissolves, you need to add a pinch again: two glasses of water - about a batch of salt. In the hot salt solution, lower the twig and leave it there for a day. Well, then - admire! The branchlet will be covered with shiny salt crystals.
