Everyone knows the easiest way to shake a grain jar is to hit it on something that won't break it, such as a roll of duct tape or a bicycle tire. I never invested in a bicycle tire and used to have a full size truck tire in my room to beat them on, so I figured this might help someone out there 
If you live near a Harbor Freight (or would pay for shipping), they have a 10" pneumatic tire on sale for $4, which are perfect for beating your jars against
