Sprouts
This is a mixture of wheat berries and mung beans in hydrated cross-linked polyacrylamide. I'm sprouting these in anticipation of an experiment we'll do in my daughter's daycare classroom. The mung beans sprouted within a few days but the wheat berries never sprouted.
Toda critica constructiva es bienvenida.
