Materials

  • Salt
  • LED bulb
  • 2 insulated soild Copper wire
  • Pliers
  • 2 Alligator clamps
  • steel wool
  • miniature light bulb base
  • miniature light bulb
  • magnesium eletrode
  • 2 plastic containers , 1 liter
  •  electrical tape
  • water

Safety Tips and Warnings

For the brightest light make sure that there is a clear path between the electrodes , that the solution is a strong one and that electrodes get maximum contact with the saltwater solution . 
 
This experiment creates low levels of electricity that , well generly deemed safe , can still cause a shock.

Procedure:

Detail steps so anyone can reproduce this at school or home










The Science behind it

Mixing salt and water does not make electricity. However, when the salt (NaCl)ionizes in the water meaning the Na+ ions and the Cl+ separates in the water, it creates an electrolyte. The term electrolyte means that the solution of salt and water can conduct electricity.


Conclusions

The more salt you add to the water the bright the bulb  will be
