1/2" PVC inner diameter? Answered
I was looking at all the excellent instructables about marshmallow guns, but I have a concern. I'm Canadian, and it seems to me that the inner diameters of 1/2" PVC pipe in the US is larger than 1/2" PVC in Canada. So, could someone in the know please straighten this out? Is there a difference or not? If so, what would be the appropriate substitute size? Thanks to all.
