In Indonesia kites are flown as both sport and recreation. One of the most popular kite variants is from Bali. Balinese kites are unique and they have different designs and forms; birds, butterflies, dragons, ships, etc. In Vietnam, kites are flown without tails. Instead small flutes are attached allowing the wind to "hum" a musical tune. There are other forms of sound-making kites. In Bali, large bows are attached to the front of the kites to make a deep throbbing vibration, and in Malaysia, a row of gourds with sound-slots are used to create a whistle as the kite flies. Malaysia is also home to the Kite Museum in Malacca.
