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).
When the outside of the didgeridoo is white and the inside red it will be even more durable. This counts for all eucalyptus didgeridoos. The sap wood protects the hardwood. The bark of the bloodwood trees look a bit like fish skin.his is a lighter type of eucalyptus didgeridoo tree that comes from the more southern and middle (not central like the desert) areas in Australia. It is not as dense as most of the trees used for didgeridoos and the wood is often light yellow in colour. The termites eat the inside out in a very clean way.
