Last winter i purchased a Polaroid Zip Mobile printer, and decided to give it a first try-out on the road, as it was intended to be used. Here’s my review, and what I learned!

Matthew DeBord/Insider

• I tested a roughly $33,000 Polaris Slingshot R, a three-wheeled "autocycle."
• The three-wheeler category includes vehicles from Can-Am and Harley-Davidson, offering a motorcycle experience in a less demanding package.
• My Slingshot R had a new, Polaris-developed, 203-horsepower engine and an automatic transmission.
• In all but three US states, no motorcycle license is required to operate the Slingshot (New York, Massachusetts, and Alaska continue to require the motorcycle certification).
• The Slingshot is insanely fun, with a modest learning curve — it's a great alternative to a two-wheeler, although the price is definitely steep for the Slingshot R.
• Visit Business Insider's homepage for more stories.

Motorcycles are cool, but they aren't for everybody. Fortunately, there are some alternatives out there that offer an equally compelling, open-air experience.

One of the most popular is the the Polaris Slingshot, manufactured by the Minnesota-based powersports company. Until recently, Slingshots were available only with manual transmissions and GM-sourced engines, but for 2020, Polaris has updated the autocycle with an in-house motor and an automatic.

The automatic transmission in particular really broadens the Slingshot's potential. So I was excited to sample the machine, which I first saw about five years ago.

Polaris was kind enough to loan me a tester for a few weeks. Here's how it went:

The Polaris Slingshot is a three-wheeled autocycle/motorcycle that Polaris industries has produced since 2014. My 2020 Slingshot R tester cost about $33,000 and was outfitted in a menacing red-and-black paint job.

The cheapest Slingshot is about $20,000.

This wasn't my first crack at a Slingshot. Polaris brought the vehicle to Insider's New York offices when the vehicle first launched.

And I generally have a gander at the Slingshot when I visit the annual New York motorcycle show.

A polar vortex brought rare winter weather conditions to the Northeast of the US on May 9, with freezing temperatures and snow reported across parts of New England, including Vermont. Up to 9 inches of snow was recorded in parts of Vermont with freeze or frost advisories reported in 20 states across the Midwest and Northeast.

Disclosed is an adhesive for a polarizing plate that comprises a polyvinyl alcohol-based resin with an acetoacetyl group and an amine-based metal compound crosslinking agent, and a method of manufacturing the same.

A method of making cerium-containing metal oxide nanoparticles in non-polar solvent eliminates the need for solvent shifting steps. The direct synthesis method involves: (a) forming a reaction mixture of a source of cerous ion and a carboxylic acid, and optionally, a hydrocarbon solvent; and optionally further comprises a non-cerous metal ion; (b) heating the reaction mixture to oxidize cerous ion to ceric ion; and (c) recovering a nanoparticle of either cerium oxide or a mixed metal oxide comprising cerium. The cerium-containing oxide nanoparticles thus obtained have cubic fluorite crystal structure and a geometric diameter in the range of about 1 nanometer to about 20 nanometers. Dispersions of cerium-containing oxide nanoparticles prepared by this method can be used as a component of a fuel or lubricant additive.
