~ submerge in water for 72 hours ~
~ after 72 hours, about 5 inches ~
When I took it out of the water, it's a little slimy. All covered by something gel-like. After 72 hours, it only expanded 200%, so I soaked them in the water for another 4 days. But it didn't really expand some more. Well, maybe just a teeny weeny bit. And the orange dino cracked up like this due to over-soaking...
