If you want to make sodium just heat table salt at about 800*C until it melts then run electricity through it. Just watch out for chlorine gas a decent amount comes out during electrosis

And you don't worry about sodium vapors or liquid sodium floating, immediately burning in air?

At the risk of spoiling all this teenage enthusiasm with a few dull facts; Yes you can make sodium- obviously someone can because the stuff's on sale.
The conceptually simplest way to make it from soda is to heat it with carbon- this was one of the first ways it was made. Of course, it's more than just mixing them up and borrowing your mum's oven.

 well sodium can be just made by heating the compound sodium chloride till its boiling point(800c)and  by performing electrolysis by using cathode and anode of graphite
NOTE:sodium reacts easily with oxygen to form sodium oxide (Na2O),while chlorine can be very harmful to the lungs []
