Science can be fun Nature reports that Sosa's cork may not be much help. Basically, it appears to be simply physics: What you gain in speed you lose in mass. (ie He may swing faster, but he loses mass in the bat so the momentum force would be about the same.) Nature also had a report of Hippo eating early man. Check out CNN's synopsis. Oh, and being a computer whiz and creating your own search engine can cost you your life savings. But none of this touches this: You can build your own CRUISE MISSLE in your backyard!!! Maybe I will turn down that stereo after all.
