**Title:** Playing with "Field Flux" (Magnetic Fidget Toy)
**Summary:**
* The host showcases a magnetic fidget toy called "Field Flux" with a metal ball that floats within a container due to electromagnetic fields.
* They attempt various trick shots with the toy, demonstrating its magnetic properties.
* A detour involves experimenting with ferrofluid, which reacts to the strong magnet.
* The video is interrupted by a series of prank calls, which the host engages with, using the magnet to "fight back".
* After dealing with the prank calls, the host returns to attempting trick shots with the Field Flux toy.
* The video ends with the host thanking viewers, vowing to block the prank caller's number, and teasing the next video.
Here are the key facts extracted from the text, keeping each fact as a short sentence and excluding opinions:
1. The device being demonstrated is called "Field Looks".
2. The device uses magnets instead of spinners, similar to a magnet fidget toy.
3. The device consists of two container-like parts and a metal ball.
4. The containers have electromagnetic fields that create a magnetic force.
5. The magnetic force repels the metal ball, keeping it centered and not touching the walls.
6. The device is based on "Lenz's Law" (referenced as "EPsilon equals Delta Pi Beta negative Pi over Delta theta").
7. The creator warns against placing cell phones near the magnets, citing potential damage.
8. An experiment with a cell phone near the magnet resulted in unexpected behavior (e.g., auto-dialing).
9. Ferrofluid was used to demonstrate the strength of the magnet.
10. Ferrofluid is a liquid that responds to magnetic fields and was formerly used as rocket fuel.
11. The magnet is strong enough to manipulate the ferrofluid into various shapes.
12. The ferrofluid returns to its liquid state when the magnet is removed.
