This is probably going to end up on thereifixedit.com - the experiment in secure packing of which this whale
was the aftermath.
Underneath the duct tape is a plastic wrap of a cardboard box. The plastic is merely to keep the duct tape from adhering to the box.
A spare styrofoam disposable cooler with its own cardboard shipping box is recycled as packing material instead of being relegated to a landfill.
Expanding foam insulation is a space-filling adhesive. Styrofoam peanuts go everywhere and are hard to clean up.
As an adhesive, the expanding foam insulation secures the lid of the cooler firmly to the container.
A second layer of expanding foam fixes the styrofoam box securely in and to all sides of the cardboard box. The whale, pre-trim, is visible as the left extrusion from the two cardboard flaps that are glued down from within.
While none of this was necessary, it became an interesting exploration of how would I pack if I was packing something both delicate and containing a substance that itself should be contained, such as a blown glass Klein bottle filled with saffron.
