Materials:

1x 250 ml beaker

1x 250 erlenmeyer flask

2x office two-part binder clips

2x lengths of wire for connections

Directions:

Prepare materials as outlined above.  Straighten the binder clip so the entire length is unbent, then drop the binder clip into the erlenmeyer flask. Place at the desired electrode length, making sure that some of the clip remains exposed above the lip for the end, plus enough to fold over. Bend the portion of the clips visible above the lip of the flash over the side of the flash and crimp them tight with your fingers (be careful not to crack the flask if using pliers) .  Next, take the wires, and form a loop around the external ends of the binder clips. Fold the ends of the binder clips over this loop, and compress with the pliers. Finally, invert the erlenmeyer flask into the beaker. Congratulations, you have a poor man’s electrolysis apparatus!
