You might have seen various kinds of swings but here we will make our doll swing on an electric swing. 

You need a 1.5V battery, a small copper rod, some copper wire, pencils rubber base, and a strings and magnet.
Make a small rubber base and put the battery at one end and magnet at the other. Clean the ends of copper rod and copper wire with sand paper. Attach the end of the copper wires to both the ends of the rod. This makes the bottom of the swing. Make the swing with pencils and wooden stick. Attach this copper rod on the swing so that it hangs just above the magnet. Connect one end of the copper wire to the battery. Leave the other end unconnected.

Now our swing is ready to rock .Mount the doll on the swing. Now take the unconnected end of the wire and keep tapping it on the other end of the battery. You will see the doll starts to swing. 
Current passing through the copper rod creates magnetic field around it. This field interacts with strong magnet and get repelled or attracted causing the rod to get pushed. You might have to reorient the strong magnet in case you can’t get the rod to swing.
If you keep the wire connected to the battery the rod will get permanently repelled and so it won’t swing. By periodically repelling the rod we make the Electric swing work.
Is it not amazing? So make and play with this amazing electric swing. This work was supported by IUCAA and Tata Trust.
