ever wish you could add more weight to the stack on your favorite machine? I found a way to add another 135 pounds or even more. you just slip this on the stack and add plates.
same with alexander graham bell and the telephone. he didnt invent it, some other guy did but he hurried up and got the patent for it....
heres a true story...one of my highschool teachers came up with the idea of having a camera on a rollercoaster and take your picture when you start going down the hill. The patent was gonna cost him a few grand however so he had to pass it up.
