Faith: you have a handy-dandy angle-of-repose kit in your possession. I have the delivery receipt from FedEx. There is everything you need in that kit, except for water, to do angles of repose until you are exhausted.
YOU DON'T HAVE TO READ ABOUT IT.
YOU CAN DO THE FREAKING EXPERIMENT YOURSELF.
Please, just for sweet, gentle Coragyps, do the experiment yourself, or just shut up about angles of repose.
If you need sea water instead of tap, give me the analysis of sea water from The Flood, and I will send you a mix of salts to prepare some. Well, unless it contains dissolved Gopher Wood.
"The Christian church, in its attitude toward science, shows the mind of a more or less enlightened man of the Thirteenth Century. It no longer believes that the earth is flat, but it is still convinced that prayer can cure after medicine fails." H L Mencken
