Those 'just add water and watch it grow' toys have been a staple of kids for years now. But if you thought you outgrew such a childish novelty, ThinkGeek might change your mind with this wonderful desk toy that brings the Incredible Hulk to life with nothing but a container full of water.
Patience is a virtue, though, because while the Hulk will eventually break free from the chamber where he's been imprisoned, it will take somewhere between 24 to 48 hours for him to absorb enough water to outgrow his way out. So once you add water you better be prepared for a round-the-clock vigil so you don't miss his great escape.
Still, for $14 it will be incredibly exciting when he finally does burst through, leaving you with a lovely diorama as a memento of all that anticipation. [ThinkGeek]
