The site even has instructions on the correct cry, which made therapist.
So, you first need to decide what kind of sound the user wants to send to Iceland. Then he was advised to stand up straight, feet hip distance apart. You should slightly bend your knees and relax your shoulders. You can put your hands on your hips.
Then the user has to do a few deep breaths and shout or say the sentence.
