We owe you the answer to our Geo Quiz today. Jake Shimabakuru's ukulele is made out of the wood of an acacia koa tree. That koa tree is native (endemic) to several of the Hawaiian islands. So Kaua'i, O'ahu, Moloka'i, Lana'i, Maui and the big island of Hawaii are the answers to our Geo Quiz.
Extra credit: if you guessed that the ukulele is based on a small guitar-like musical instrument called the "cavaquinho", brought to the Hawaiian Islands by 19th century Portuguese immigrants, then give yourself a pat on the back.
