Hmm sand and bamboo how would you do that ?...
Well, my first thought is that sand is SiO_2, so you could try to
reduce it to silicon and make transistors.
We'd not be able to make transistors with just sand. There are
essential doping agents. I'm not sure arsenic can be easily extracted
from bamboo...
