Most of the questions we get asked are about the animals and the way they behave. "How many teeth do your sharks have?" "How fast can an otter swim?" "What does a paddlefish eat?" But sometimes we get asked, "How did you do that?" To see the gentoo and macaroni penguins clearly you need some big windows. In the top picture you see a huge acrylic panel that had to be hoisted into Ocean Journey with a big crane. The bottom two pictures show some special construction workers designing and creating the rockwork with concrete. It's a job worthy of the television show Dirty Jobs.
