Ink can be removed with cheap hair spray or alcohol. Saturate the spot well and rub it out. Repeat until it comes out. If the shirt is white, you can use a bleach pen too. I once had an entire pen bust in my pocket. My teacher told me out Murphy's oil soap on it wipe off and then put clothes in washer with Murphys, worked like a charm.
Take it to a dry cleaner; if they can't do it they may be able to recommend someone who can. Honestly, trying to do it yourself is more likely to mess it up further than to actually fix it.

Ball ammunition has a solid copper or steel jacket (full metal jacket), completely covering the bullets core, usually made of lead. The base, or back of the bullet can be exposed lead. If the base is jacketed in metal as well, it's known as a total metal jacket. The Geneva convention dictates that all small arms ammunition used in armed conflict be ball ammo, in order to avoid the truly catastrophic injuries that result from hollow point, poisoned, cross tipped, soft point,etc...
The leather ball bounces because it is full with air in it. If you remove the air then the leather ball does not bounce at all. While the aluminum ball (which I can only imagine, since I have not seen any aluminun ball before) will bounce, with or without air.
hard leather
regular everyday soccer ball has 32 leather panels. 20 of these leather panels are regular hexagons, while the other 12 leather panels are pentagons
A real Baseball is made of coark and rubber. The outside of the ball is leather. A fake baseball is made of wood and a leather outside.
A leather basketball is better than a rubber ball but if your playing outside the ground ruins the leather so a rubber ball is better when you are playing outside

The leather is put on the basketball for grip, wear and tear, and consistency. The bounce of the ball comes from the rubber bladder that the leather is surrounding. Air pressure and the quality of the ball effect it's bounce more than the leather.
