I've already tried picking dandelions. The latex that you get from them is very limited, but you CAN make a rubber band, or a pencil eraser, if you get enough.
How does one get latex out of a sweet potato? Does it come from the vine or the tuber? How would you extract it? Any other temperate-zone plants with milky sap that dries stretchy, not sticky or gummy or sugary...?
BTW, I've read numerous bios of GWC on line and in libraries. While they all say he turned sweet potatoes into gasoline and rubber, etc., none of them give details. Did he actually succeed, or was he just thinking about it?Are the processes patented? I just want a small scale demo.
Please, serious answers only. Thanks everybody.
