Hi Al, I would appreciate if I could get the sliced up styrofoam ball again. Also: Bob Jones mentioned that you may have a model of a dipole and also a q-tip and foam ball model for electric field lines around a charge: of so, could I please have them for tomorrow ?)

Hi Al, I would appreciate if you could get the beach ball, a basket ball and a soccer ball (if you have any) for Monday. Also: if you have small metal-foil pi-plates (like the ones in the stock room for keeping nuts and bolts in the lab), I would like to have about 5-10 of them. What I need is not the smallest size, but the one with a diameter of about 6 inches.

Hi Al I would also like to borrow the bicycle wheel for show and tell. also, is there an easy way to show the current when the terminals of a "D" battery are connected with a wire ? compared to when the terminals of a car battery connected with a wire (like in the jumping wire demo, but in this case current going through a ammeter projected to the scree) ? If this can be done, I would appreciate if you could get it for me Thanks Nilanga

Hi Al Do you have a pair of magnets that I can pass to the student to show how strong the force is ? Also, I see Bob Jones notes, something like "hang from electro-magnet" what is that ? If it is not too much trouble, I would like to have these for tomorrow. Also I would like to have some paper clips with the magnets also.
