Suction-cup glass markers are a simple way to cut back on dishwashing

markers

My kids are in the habit of using a new glass every time they get a drink of water. As a result, the top rack of our dishwasher fills up much faster than the bottom rack.

I bought a set of 13 squishy rubber Creepy Creatures suction-cup glass markers ($4) so everyone in the family can claim a water glass for the day. These markers were meant for halloween party wineglasses, but they stick to water glasses any time of the years. We keep them on the tile backsplash under the glass cabinet. markers-2

Photos of bugs and stuff with my USB microscope

I bought this USB microscope for $40, because I want to examine kitchen knife edges after I sharpen them using different sharpeners (I'm going to review them for Cool Tools). I'm having a lot of fun with it. The tiny millipede above is in a cup the size of a penny. Here are some images I've captured so far.

Mercy Watson: Adventures of a Porcine Wonder

Mercy Watson Boxed Set: Adventures of a Porcine Wonder

This collection of Mercy Watson books is all my seven-year-old daughter wants to read. They are cute stories with thoughtfully challenging vocabulary.

Mercy Watson is a pig who lives with her adopted human family. She loves toast with a great deal of butter and has wonderful adventures. The stories are entertaining enough that as an adult listener I chuckle quite often. The vocabulary and character names are well chosen, requiring a bit of effort but expanding her grasp of our language.

We had a hard time finding books that Hannah wanted to read. Now she reads me bedtime stories.

Birdscapes: A Pop-Up Celebration of Bird Songs in Stereo Sound

I’m filled with wonder at the engineering and imagination needed to create the magical eye candy of pop-up books. Elaborate scenes come alive as I unfold each page. I’m always surprised the first time I open a pop-up book, but with Birdscapes more than my eyes were opened. There are bird songs and bird calls, tweets and warbles, sounds of nature from the Arctic Tundra to the Great Plains of North America – all in stereo from the back pages of this book!

Birdscapes presents seven intricate, delicate and very realistic pop-up bird habitats along with the sweet melodies of the birds that live there. Each soundscape is pared with text about ecosystems and bird species that’s easy to follow for the novice and specific enough for the expert. Spotted Owl, Western Meadowlark, Ruffed Grouse and even a Woodpecker are seen and heard. This is definitely one book filled with lots of oooh and aah moments.

Batteries are included in the book for long lasting listening pleasure. – Carole Rosner

How to win at rock, paper, scissors

In 2005 a Japanese electronics firm decided to sell its collection of four French impressionist paintings. Christie’s and Sotheby’s courted the company. The CEO asked the auction houses to play a game of Rock Paper Scissors to determine who would sell the paintings. The representative for Christie's researched Rock Paper Scissors strategies, and used the advice of one of his co-worker's children: “Everybody knows you always start with scissors.” This proved to be good advice in this case, because Sotheby's chose Paper. Christie's sold the paintings for $17.8 million, and earned a $1.9 million commission.

William Poundstone (author of many books I've enjoyed, including Big Secrets, Fortune's Formula, Prisoner's Dilemma, and an entire book about Rock Paper Scissors) starts off his article about Rock Paper Scissors strategies with the above anecdote. He looks at strategies involving statistics (in pro tournaments Rock gets thrown 35.4%, Paper 35%, and Scissors 29.6%), doublethink, tells, scripts, and pattern recognition. His conclusion:

  • Scissors is the least popular choice, and men favour rock. Both are reasons to choose paper in a one-shot match.
  • Announce what you’re going to throw and do it. Most players figure you won’t go through with it.

Leif the Lucky – A gorgeously illustrated bio on Leif Erikson, the first European to set foot in America

Leif Erikson, the Viking explorer, is usually just briefly touched on in elementary school classrooms. But his rich story is a captivating one that any child – or adult – would enjoy. As a boy he moved from Iceland to icy Greenland, where his father established the continent’s first settlement. Eric grew up learning how to sail ships, throw spears, and catch sea animals for dinner. He played with baby polar bears and dreamed of adventures.

As a young adult Leif sailed to Norway and charmed the king with a Greenland falcon on his fist and a bear cub at his side. The king granted him permission to explore the west (Leif’s father had once seen a speck of something west of Greenland on an earlier exploration), and Leif became the first European to set foot in America (Canada) – 500 years before Christopher Columbus “discovered” it. Soon Leif’s relatives settled in this new land – for a while – until, well, I won’t give the whole story away, but let’s just say they were chased off the new land and forced to hightail it back to Greenland.

As soon as I laid my eyes on this book I was blown away by the stunning art: the bold popping colors on some pages, the beautifully shaded black and white images on others, and the saturated details and texture that all of the illustrations enjoy. And then I found out the book was first published in 1941 by Doubleday, created by the bohemian husband-and-wife team Ingri and Edgar Parin D’Aulaire, who wrote 27 illustrated books in all (many of them tales about Scandinavian heroes and mythology). Leif the Lucky is one of three of their books to be reprinted by University of Minnesota Press, and I now need to get my hands on the other two (Children of the Northlights and Ola).
