We  had our success! After a lot of tries we had finally got it.We got to have a special cup that could hold the most marbles.After we put all the marbles in we tested to see if it could keep levitating.It barley worked it  was efficient but not very safe . what we did was we put strip magnets in three rows of three.It made it levitate so much higher then one. After hat we used a special cup to  hold more marbles. We finally got it!
