MINNEAPOLIS – No matter how you spin it, the fidget spinner craze is becoming big business.

According to 1010data, Inc., a company tracking e-commerce data, the number of fidget spinners sold online in April is 127 times greater than the number sold in January 2017. Google Trends shows the search volume for ‘fidget spinner’ is rising to the number of searches for President Donald Trump.

As stores sell out of the gadgets, the search for spinners has become homegrown.

In Crystal, Caleb Ley, 14, fashioned his own out of bearings from his skateboard.

“There’s over 1,000 videos on YouTube on how to make them. That’s what my friends said I should do, make these and make a profit,” said Ley.

In Brooklyn Park, Gabrial Reigger, 14, started 3-D printing fidget spinners in his basement after he and a friend came up with the idea at lunch, knowing how many of their classmates wanted to buy the gadgets.

Reigger got a loan from his father, and has already paid off that loan from the sale of the fidgets.

In Minneapolis, another type of fidget is about to hit the market, started by a student team at the University of Minnesota Carlson School of Management, who spent months developing a silent fidget designed specifically for the classroom.

Senior Anna Wetmore, a self-professed fidgeter, came up with the idea of the pencil topper fidget, called a Toppi.

“We are all students that saw this as a problem personally but also with peers in the classroom, we wanted to create something for other students, but really wanted to steer away from creating a toy,” said Wetmore. “By using it class, it's discreet, it doesn't get them that unwanted attention, but it's also silent which is really important to teachers.”

Wetmore brought her idea to an entrepreneurship class at the Holmes Center for Entrepreneurship and her idea became a business, called Able Mindworks. Her team has sold more than 1,000 Toppi fidgets through pre-sale, and recently began manufacturing thousands more at a Stillwater facility.

The design includes a rolling ball and twisting gear and in testing the prototype in classrooms, Wetmore found a lot of students also use the rolling ball to follow along on a page while studying, a benefit students themselves discovered.

“Now we can redirect that fidgeting into a more purposeful less distracting way,” said Wetmore. “It’s amazing.”
