I enjoy any science project which uses magnets. This one here is an interesting and simple to make project involving match box cars that move without you actually touching them. Naturally its the magnetic force in action and it a great way to understand the concept of the magnetic field.

All you need is a few empty matchboxes which you can redesign as cars. Paste some glazed paper on them and draw in the details with a felt pen. Add a four wheels to each car and make a magnet sit in the matchbox in the middle.  Once your match box cars are ready you can place them on a smooth surface like a dining table to begin the experiment.

As you bring a car with a like pole close to the car before it the car in front will also start moving on its own without you touching it. If the poles are opposite then you will see the car in front reversing into the car behind. You can make them go the full length of the table and see how the distance affects the magnetic force exerted as well.

This is a game which young boys will not tire of very fast. In fact it can be even more fun if you have two sets of cars and set up a race between the participants. Have fun with science projects like this and science will never seem boring again.
