Thinner plastic allows the soil to heat up better but also tears more easily. Use plastic with a thickness of 1 to 4 mils for best results. Fill in the ditch around the perimeter with soil to hold the plastic in place. You may also wish to add rocks to the edges to help hold down the plastic.
The didgeridoo is a wind instrument traditionally made from the trunk of termite hollowed eucalyptus trees from Australia (like the one pictured at left, which is being played by our mate Lewis Burns).
Genuine didgeridoos are always made of wood, usually the smaller trunks of living, young eucalyptus trees. The species of eucalyptus did not matter. They were not usually madeâ¦ from branches. They were not made from dead wood hollowed out by termites - this is a common myth. The Aborigines hollowed out the wood themselves.
