Mise à jour du bracelet Kumihimo pour ajouter des informations et un profil avec personnalisation de texte

The hair hygrometer allows you to measure ambient humidity using hair, as it lengthens with humidity! Attach the hair to the top of the cardboard and to the arrow; the arrow will then move downward if the humidity increases. This can predict rain if the humidity is high, or good weather if the air is dry. This is an interesting activity to do with children or even adults, while learning something new!
