I have 2 months, $250,000 and I can have 100% risk how do i invest?

[PhiGamTN]

So i'm taking an investments class and one of our incentives for a stock market game we're playing is that the top 3 teams get very nice prizes (an A in the class) the final report on the project doesn't require us to justify our trades or to have made money... it's simply picking a portforlio of 10 stocks at the end. So basically i have $250,000 I can get a magin account with a total of $375,000
I can invest in basically anything, futures options shorts commodities etc... doesn't matter if I lose all the money or not, only goal is to make as much money as possible in 2 months or so...

How do I invest my moeny?

only stipulation is I can't invest in any stocks less then $5 although if I short them it's ok for them to go under $5
