Meriam Buluh in Malaysia has been going since the 1870s. The Cannons were originally made from hollowed out termite mounds, the explosive force coming from the volatile fumes of heated kerosene and were used to scare off large predators from the surrounding jungle so that the locals could safely visit each other on the eve of Eid Al-Fitr. These were Known as the Meriam Tanah or Earth Cannons.
As the population has slowly increased and the jungle been pushed back, predators became scarcer and the need for the Cannons diminished termite mounds were getting Hardev to Find too, and a substitute was found in the large diameter lengths of bamboo, which led to the popular name of Meriam Buluh, literally Bamboo Cannon.
With the introduction of calcium carbide by the British for use as a fertiliser in the banana plantations, stronger and mote reliable explosions could be made but the additional force meant that the bamboo could only be used once. The solution was found in the 1970s when old lengths of water pipe, salvaged from British pumping operation in the nearby Perak River, began to be used.
The tradition is bos in its 6th generation and has been around for some 140years but a lack of support from Malaysian government means that It is at very real risk of being banned as it stands the practicality is illegal and only allowed to proceed each Year due to the local police turning a blind eye( and deaf ear) to the happenings. Without proper, it will only take one serious injury for the whole event to be cancelled and Malysia will loose another piece of its cultural heritage to the apathy of its its ruling class.
