Jacob's Ladder
Fascinating depiction of the power of static electricity.
Supplier: Science First 6154670
Description
Also called climbing arc, Jacob's ladder is best known for its role in Frankenstein movies.
- Power supply creates a powerful voltage potential (15kV) between two brass electrodes, enough to ionize the air between them and turn it into plasma
- Plasma is conductive, allowing an electric arc to complete the circuit
- The arc dances up the electrodes, carried by rising convection currents
- Electrodes slant outwards; eventually the distance between them is too great to sustain the arc, which dies, only to form again at the bottom
- Electrodes are shielded by an extra-long, sturdy polycarbonate tube
- A lid allows hot air to escape the tube, but prevents objects from being inserted
- Each electrode is capped with ceramic to ensure the arc is extinguished, while a built-in fuse prevents overloads
- Maximum current is three microamperes, insufficient to cause injury
