How can I temporarily support a PVC pipe in use as a delivery mechanism?
I'd use whatever stool or chair you have around at the low end, and a stepladder or similar at the high end, possibly just leaning against the exterior wall outside the door. Cable ties, string, or duct tape would secure the pipe well. A little weight on low rungs could add stability.
I love this idea and may borrow it myself (or some Rube Goldbergian variation). A sign on the street promising &quot;no contact&quot; and that &quot;we wear gloves&quot; might add a level of comfort. Of course, I'll still don my Pennywise costume (with balloons) and emerge from the shadows alongside for a sweet/sour thrill on the turnaround.
By the way, a 4&quot; pipe is huge and heavy (unless you use the thin-wall sewer pipe, but it's still larger than you need). 3&quot; is probably just fine, and for your specific candy 2&quot; would probably do. You might even get away with 1-1/2&quot; thin-wall central vacuum pipe.
