Make a Didgeridoo out of PVC Pipe

A didgeridoo is a simple but fun instrument that you can make out of plastic pipe.

Steps

Buy a length of 1-1/2" PVC pipe from five to six feet long. The length will determine the pitch of your didgeridoo. It's easier to estimate longer, you can always cut it down. A length of 51.5" (including the mouthpiece) will tune your didgeridoo to a low C.
Buy a Female-Female 1-1/2" coupler piece, and a 1-1/2" to 1" bushing. This will make the mouthpiece.
Clean the cut edges of the PVC pipe. These tend to send off ribbons and hangnails that will only impede your airways. A wire brush is ideal for this task, but you can shave off excess PVC with a pocketknife if need be.
Assemble your instrument. Place the coupling firmly onto the end of the pipe. Fit the bushing into the coupling. You now have an assembled didgeridoo!

Buy a {{safesubst:#invoke:convert|convert}} diameter PVC pipe that is {{safesubst:#invoke:convert|convert}} long. Get a block of beeswax, acrylic paint, a bulb planter, a glass beverage bottle, a rounded head bolt, and a hot air gun.
Take the pvc and heat the end until it is all loose. Then stick the glass bottle in it. This will begin your bell. Let it cool down, then heat it again and stick the bulb planter in it with wd40 on it first, then that should give you a bell.
Heat any area and press the head of the bolt on the heated pvc. Do this everywhere.
Take a rough grain sandpaper and sand the pvc, then prime the pipe let it dry.
Paint your didgeridoo with the acrylic.
Make your mouthpiece out of the beeswax.
Give it a blow!

Tune your didgeridoo by ear - the length determines the pitch.
Decorate your didgeridoo! Paint it, plaster things onto it, make it a visual object of art as well as a sound machine. One creative way to decorate it is to use a propane blowtorch to roast it like a marshmallow. When the tube is hot you can put slight bends in it as well. Wipe it down with a wet rag and the final product will look more like a piece of wood than a PVC pipe.
Advanced didgeridoo players may choose to make a mouthpiece out of beeswax, to make a more custom fit for the lips. Wax molds better to the mouth than plastic, but this simple mouthpiece can get you started.
You may find it more comfortable to use a coupling with a slight angle, perhaps 22.5 degrees, so as to play through the side of your mouth. It's a whole different technique!
While using a heat source to bend PVC pipe, the pipe should be filled with sand to prevent wrinkles and creases.

If you wish to use heat to bend or twist your PVC didgeridoo, be absolutely sure to do it outside! PVC releases toxic fumes when heated, and bad things could happen to your lungs if you inhale too much of the vapor.
You may wish to wear a dust mask or respirator when working with heating the pipe, but these may not provide full protection from the toxic vapors. It's worth mentioning again, ALWAYS work outside when heating PVC!
If you're using a blow torch observe all warning labels on the fuel tank and nozzle! Propane is dangerous and must be used with caution.
A hardware store may only allow you to buy a ten-foot length of PVC pipe, but they will usually cut it for you if you ask.

- - If you value your liver, and do not want to die early, DO NOT SCORCH PVC. DO NOT breathe ANY off gassing from heated PVC! It is an extremely potent carcinogen. We are not talking cigarettes... we are talking straight up poison. A "mask" will not protect you. Even for heating to bend, you should wear a properly rated chemical respirator, and do it outside!
