devices. Ever heard someone say - "It'll work in a pinch" ? List stuff from the hardware store,common household items, or any fruits or vegetabes used to help catch one. I'll start - Made a pipe out of an apple once,it handled the task at hand and had a nice after taste.
you can make a shitty pipe out of a million things. tin foil, pens, corks, sockets, etc. The question is why.
my friends made giant steamrollers out of the things their school pictures came in. they have their names printed on them.
Made a 4' bong out of PVC in 1976,it took at least two people to smoke it. One to give fire,and the other to toke hard. The first hit would blast lungs,but it got better with the second.
The reason why is so that people who dont have or know where to get good pipes use the resources around them and still get that groovy effect
