Marine experts are trying to understand why one rare seal spends its day spinning.

Maka Onaona learned the trick when he was younger and aquarium staff believe he may be trying to relive his youth.

One dad wanted to build something cosmic to inspire his 16-month-old, so he built him a homemade spaceship. Daniel Sherrouse of Gadsden, Ala., constructed the spaceship simulator in his backyard for his son, Noah. The simulator is built inside a small trailer that he purchased and decked with radars, computers and blinking lights. After all his hard work Sherrouse joked saying, "hopefully his friends will think it's cool and not make fun of him for having a spaceship."
