PVC tubing would likely work very well. It's not necessary to use any
adhesive on "temporary" applications. The fittings are tapered so that
a water tight seal can be made simply by pressing the fitting and tubing
firmly together. A simple developing tube could be made using a short
length of tube and two end caps. Most consumer oriented lumber
yards/home centers will sell PVC tube by the foot. Buy one foot of tube
and two end caps. It could likely be done for less than $10.
