Rose of Bread, explains Amon Yariv, is made of Bread on a wire.
"The flower is in a plastic bottle and the water is yellowish because of the wire's rust. Yariv is telling us about what prisoners in old Russia where doing while in prison. They were using plain bread and kneading it, leaving it in water for few days; then they were coloring it and flattening it into small red and green leaves. With these they assembled the "flower" head on a wire and when their Girlfriends came to visit they handed it as a gift."
