We took a tour of Uncle Milton‘s latest offerings at this year’s Toy Fair and they’ve expanded into a Marvel Comics Science line for 2013. This is the Transforming Hulk toy. You put the tiny Hulk in his cage into a container of water. The Hulk expands to 4 times his original size and in doing so busts out of his underwater vault. Pretty cool- obviously expand-in-water toys have existed for years but the vault part is a unique twist on the classic. You can wring out the figure and reuse him (the vault is single use however). Look for it in stores later this year.
