Introduction: Coconut Shell Ashtray
This is a cool repurposing of a natural object, a coconut. After you finish drinking the water and scooping out the meat to eat, you are left with a shell. I use a hammer and screwdriver to split the coconut into two pieces. If you have a bandsaw, that might be quicker.
If you want to get fancy, you can cut out half-holes on top to place cigs or joints. The coconut also has a nice odor which may reduce the odor of the ashes.
