You have to ask users to store the 11 character code from the youtube video.
Do not store the embed code in your database -- YouTube may change the embed code and URL parameters from time to time. For example the embed code has been retired in favor of embed code. You should parse out the video id from the URL/embed code (using regular expressions, URL parsing functions or HTML parser) and store it.
Then display it using whatever mechanism currently offered by YouTube API.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
