Everyone is right. The arm was made out of noodles and potato. After standing for a few days kugel gets hard but can be carved. Excellent resonance rejection because its made out of a single chunk of kugel carved to the right shape. Same idea as the recent VPI made in a 3D printer.
The question is what kind of kugel makes the best arm. It's very personal, typically based on what you like best. I like a sweet noodle kugel.
