This product is a replica of the Alessandro Volta device: it is composed of galvanic cells connected in a series to constitute a source of electricity. Zinc and copper washers are stacked alternately onto each other and separated by a felt washer soaked in an electrolyte (salt or acid water) allowing the electricity to pass between the layers and thus measure the voltage between the two ends of this stack.

Composition :

• 1 Volta battery consisting of 10 zinc washers and 10 alternating copper washers
  
• 1 receptacle to collect excess electrolytes
  
• 1 box equipped with 2 safety banana sockets
