Abstract :
A dust plasma was created using spores in a glass discharge tube. The dust particles become negatively charged, levitate in the positive plasma potential, and behave like massive electrons. A laser beam is used to make the dust visible, revealing plasma structure, such as the wall sheath and the direction of the local electric field
