Eisco Labs Electrophorus Demonstration produces a strong spark repeatedly, without recharging. The base is thick plastic with four rubber feet attached for convenient handling. The plastic material produces a strong frictional charge when rubbed with fur or other material due to the triboelectric effect. The 9 cm diameter aluminum plate is designed to eliminate any sharp edges which could cause leakage. An insulating handle is attached.
