Two Harbors is the place where 3M was founded. Don't know 3M -- bet you will recognize some of these products.
This story is told in the building in Two Harbors in which the company first had its office. I went to visit here later in the afternoon after completing a 10 K walk in Two Harbors, reported in a previous post.
I learned what saved the company was the invention of Wetordry sandpaper.
In the museum I learned of two products that surprised me.
Another product is stickers to put on butterflies to track their migration.
In another room in the building there is a display about 3M international presence. A large sign lists the various countries in which 3M does business and the date it began in each country. With my interest in Central Europe I looked for those countries.
