So this picture was from my attempt to manually cryogenically grind black walnut shells in liquid nitrogen to turn them into dust. I was doing this because they are extremely hard and had read about cryogenic grinding (on Wikipedia), so I attempted to cryogrind them to pulverize them into dust. I was conducting bomb calorimetry experiments to ascertain the caloric value of burning waste walnut shells. This was for a final project in a college physical chemistry lab course.
