Struggling with my idea

Recently my original idea for senior project was to get a grant for the school to upgrade our science department by buying new equipment and textbooks and other necessary things for science classes.  After further discussion with some advisors the suggestion came up that I should "explore other options." I am still in the process of coming up with new ideas for my project and my goal is to have my idea by this Friday.  I have some ideas but I am still struggling with the fact that I have no project idea yet!! Hopefully I can come up with an idea that will be interesting to me and that will benefit someone.  Fingers crossed!!
