Inverted Globe - Finding Wilson

One of the stars in the movie 'Castaway' is a volleyball called 'Wilson'. While leaving the island Wilson and Tom Hanks became separated - hence the 'Wilson' call from Tom.

But where was the island Tom and Wilson were marooned on for over 4 years? Later in the movie we learn the plane goes down 600 miles from the Cook Islands. By drawing a circle around these islands with this radius we can see the likely area. It covers over 1000 square miles of surface area.

This area can be more easily viewed using an 'Inverted Globe', unlike a normal globe, where the surface slopes away from the viewer, its slope towards the viewer's eye, making the surface easier to view.

The 'Inverted Globe' has other advantages:

1. It's half the size.

2. Doesn't roll around.

3. Can also be used as a fruit bowl.

The inverted globe can be repositioned so any place on the earth's surface is central.

Inflate an Inflatable globe in the usual way.

Make an incision into the inflated globe and cut (almost) halfway around the circumstance.

Do this on one of the longitudinally lines to hide the cut.

Insert a bowl of the appropriate size into the cut globe.

The cut is closed with a series of gaffer tapes, stuck from the inside of the globe.

Once the bowl implant operation has been completed, the inverted globe is ready for use.
