Materials:
A lemon, or other citrus fruit
18 (or smaller) gauge copper wire
Wire stripper/clipper
A grown-up or older friend
Steel paper clip, small galvanized nail (one that is covered in zinc), or a piece of zinc (ideal)
Procedure
Ask your grown-up to use the wire strippers to first strip about 2 1/2 inches of plastic insulation off the copper wire. Then, request that the grown-up clip that piece of stripped wire off of the main roll.
Carefully straighten the steel paper clip. Use the wire clippers to cut it to the same length as your copper wire.
Use the sandpaper to rub out any rough spots in your wire or paperclip. You are going to be touching the wire ends to your tongue, so you want them to be smooth. If you are using the zinc covered nail or piece, scratch it lightly with the sand paper to expose a fresh surface.
Roll the lemon gently on a table to break the cell walls and loosen up the juice inside. The sour juice is needed for the chemical reaction that you are about to start. The fact that the juice is sour should give us some hints about what kind of chemicals make up lemon juice. What do you think the sour flavor might tell us?
Carefully stick the copper wire about 1 inch into the lemon.
Make sure your tongue is moist with saliva, or spit. Touch your tongue to the copper wire. Do you notice anything?
Stick the paperclip, zinc covered nail or zinc strip into a spot in the lemon about 1/4 inch away from the copper wire. Make sure the wires don’t touch. The wires n ur bettry is ready
