How to make a penny battery, Voltaic Pile easy science Project

How to make a penny battery is a simple science project to understand the generation of electricity is one of the easiest to make and the raw material is available.

This simple school project uses two different types of metal which is stacked one on top of other and use some salt water or lemon drops to make a voltaic pile.

These kind of simple batteries convert chemical energy to electrical energy and generate small volts electricity. The higher the stack then higher is the voltage produced which is enough to light up one small LED of 1.5v.

Zinc and copper are the materials generally used for this school project. Zinc nails and copper wire can also do the trick.

Usually pennies are used. They are first sanded with sandpaper on one side so that zinc can come to surface and the other side is usually left free. Copper side is faced down and zinc side faces up and in between them a tissue paper soaked in salt water solution or lemon juice is used. The stacking is done the same way by placing copper side of the penny again on the zinc side with tissue paper soaked in sour solution to complete this science project.

Vinegar can also be used to soak tissue paper to make the pile. The stack can be as big as 12 penny pieces to generate minimum voltage to give electricity to light up LED.

It usually takes 7 to 8 hours for electrons to start flowing for science project to work. The tissue paper should not dry in the process and is kept wet with the sour solution.

The stack can be made higher once the voltage is checked from the multimeter.

There is another variation to this whole project as in India the pennies are not easily available we can use zinc nails and copper wire to compete the project.

How to make a school project magnetic crane without using an electromagnet?

Hmm, we have one DIY kit for making a magnetic crane using electromagnet (http://www.projectsforschool.com/product/magnetic-crane/); and a how to make guide for the same as well (http://www.projectsforschool.com/product/making-magnetic-crane/).

But if we want to make a magnetic crane with out using electromagnet, then we can replace the electromagnet with a simple magnet. You need to make the frame for the crane using wood / plastic. Then instead of electromagnet, you can use a simple magnet to lift and move, and manually drop the iron / steel objects. Electromagnet provides the option to drop the objects remotely by switching off the current.

A crude model of magnetic crane can certainly be made using a simple magnet. Readers views, suggestions and comments are welcome.
