Look at the size of that thing. That, kiddies, is why they call it the Power Cosmic.
Kidding. It’s actually a ten-foot model planet Earth (weighing in at 26 tons), put in place by geophysicist Dan Lathrop to try and establish how planets get magnetic fields. He’s going to fill it with liquid metal and set it spinning to see if it creates such a field.
The top speed it will reach is 80 miles an hour. Although since his lab appears to be on a university campus, they can probably legally only take it up to 15.
