The other day, my daughter was playing with some Orbeez (which are these little, desiccated, super absorbent polymer spheres that grow several times their original size when moistened).
"Well," I thought to myself, "these would fit in a p-valve hose readily." The p-through bolt could be easily removed and 2 or 3 Orbeez inserted. They would be of sufficient caliber as to not fall out once the bolt were replaced. The great part is the p-valve would seem to work fine when primed upon first use, but after several minutes, relief would not be in sight.
