The electric plug was invented by Harvey Hubbell. It was patented in 1904 with the first design being a socket that screwed into a lamp.
The extension cord was invented in 1904 by S. W. Atherton, an American inventor and electrical engineer.
normaly we can use water proof extension cord
No. However, a longer extension cord has higher resistance for a given wire gauge or size compared to a short extension cord and the voltage at the load device may drop so low that it doesn't work properly. This may also be accompanied by a noticeable rise in the temperature of the extension cord. As a rule, use the shortest extension cord that will get the job done. If the extension cord must be long, use one that has heavy gauge wire to minimize voltage drop at the load.
#16 <<>> To load an extension cord to 1725 watts depending on the length of the cord, the bare minimum should be #14. A better size cord and my recommendation would be a #12 wire size extension cord.
The most number of outlets on a multi outlet extension cord are six. Any more then six outlets on an outlet extension cord and it would become dangerous.

An extension cord holder is used to hold an extension cord. It wraps around the holder, for easy release and withdrawal.
Yes, it safe to touch a extension cord while its plugged in.
Yes, you can put the iPod Touch wall charger into an extension cord. That extension cord has to be plugged into a wall to be able to charge the iPod, though.
