A company is looking to real UFO cases to inspire its line of spinning tops.

Provo, Utah—based company Plexity Labs is creating metal spinning tops based on documented UFO sightings. The current offering includes craft described from three different UFO cases: The Roswell UFO Incident of 1947, the Cussac encounter of 1967, and the 1980 Rendlesham Forest Incident.

The three tops look cool. But they also come with details about the UFO cases on which their design is based.

The company launched a campaign on the crowdfunding platform Kickstarter with a goal of raising $1,980 for the manufacturing of these UFO tops. The campaign was fully funded within a mere 72 hours. At the time this story was published, more than $4,000 has been raised.
