Hey, it's been a long time I posted anything, but this summer I sunstretched a whale and never posted this picture that I took afterward. I wasn't sure how much difference there was so I inflated two whales to compare, they are different models but they originally had the exact same size. And if you're wondering why the back didn't get all round, I've over-inflated it under the sun while sitting on the back where all the expansion goes otherwise.
