Guatemala Hearing Aid Presentation

Yesterday, my teacher's mom came in to talk to us about hearing aids! Every year she goes to Guatemala to put hearing aids into peoples ears. It is amazing because some people may have never even getting a chance to hear, hear. She must feel great after helping all those people!
It was really fun, she made a hearing aid for our teacher by mixing together some play dough like mixture and putting it into a tube then compressing it into her ear. Then we waited till it hardened and took it out. It looked kinda funny because you could see the part where her root canal fitted.
Here is her Blog!
Here are some pictures of Guatemala (she did not take them though):

Beautiful Antigua, Guatemala

This (I think) is one of the hospitals she went to
