Instead of tubing, bamboo works well since the nodes give a natural closing on one end of the tube. 

Begin by getting approximately 65 cm of 1.3cm/schedule-40 PVC sprinkler pipe.

1) Cut the tubing into the five sections above

2) Place a 5 cent coin over one end of each pipe and cover each with a square piece of duct tape.

3) Wrap duct tape around the set as shown below. Blow across the top of each pipe — it's just like blowing on a soda bottle.

You can also take thinner bamboo sticks and lash the pan pipes together
