Digital LCD display with short wire leads. Pk/10 (TS2047)
These digital LCD watch displays have been modified to enable teachers and students to use them to demonstrate electricity generation using lemons, potatoes or other fruit or even play dough.
Each digital LCD display has two short wire leads attached to the unit thus making it easy to connect to electrodes inserted into a lemon or a potato. (Or even try mixing a solution of citric acid or experiment by using other fruits)
If you want to demonstrate an Earth Battery contact us regarding how to use these displays to demonstrate this phenomena.
