Red ball - a symbol of the fact that there will be difficult! After all, red refers to all things that are either very dangerous or very difficult. Today you will need to remember all the laws of dynamics as well as on the movement of different things. You will need to throw the right side of the playing field ball to the left side, so much so that he caught the dates you "shelves." All shelves, which will be on the playing field - are marked with numbers. You need to throw so that the ball hits them in order. Good luck to you!
