The creator of the CodeParade video channel made an interactive pushbutton busyboard for his toddler.  He bought a bunch of knobs and switches, wired them to an Arduino, LEDs and beepers, and put them in a craft box. It has a simple mode, in which pushing a button triggers a sound or light, and an advanced mode, which includes a Simon game. It looks like something people of all ages would enjoy playing with.

My In-Laws Are Careless About My Deadly Food Allergy is a letter sent in to The Cut's Ask Polly column. It's the second-most amazing agony aunt letter I've ever read.

I have a very severe allergy to mushrooms ... Since then, most meals we have shared at my in-laws’ house have had very limited options for me. Somehow, they manage to find a way to add mushrooms to almost everything. One time, they made a point to make a special plate of mushrooms and pass it around. My mother-in-law said, very rudely, “I would’ve liked to add mushrooms directly to the salad, but SOMEBODY has problems with it!” They even added mushroom powder to the mashed potatoes at one holiday dinner. My mother-in-law claimed it was a new recipe she’d found.

This is just the beginning; it'a rollercoaster ride into mycological madness.

Following is my number 1, posted by Slate's Dear Prudence in 2012. First, the shot...

My mother-in-law hates me ... the problem is that after each visit, I wind up with a bad case of diarrhea; my husband does not. I don’t know if the other in-laws are affected, because if I asked, it would get back to her. I suspect that my mother-in-law is putting something in my food or drink.

Then the chaser.

You had suggested swapping plates with my husband to see if my mother-in-law would react. However, as you noted, that would have required bringing my husband into my confidence. I did not feel it was wise to do that, because he already didn’t believe that his mother treated me badly.

Quantum Physics for Babies and Rocket Science for Babies are the kind of board books you’d find on a toddler’s shelf. They have stiff, tear-proof cardboard pages, simple illustrations, and minimal text. But they actually explain the subjects on a (very) high level. The author, Chris Ferrie, is a physicist and Senior Lecturer for Quantum Software and Information at the University of Technology Sydney.

I finally learned why quantum physics is called quantum physics! And even though I know how a wing moving through air goes up, the rocket science book reinforced the concept for me.

These books will be entertaining for kids age 2 and up, but the concepts, even though clearly and simply presented, are better suited for readers from age 5-105. Read the rest

Even as an adult, I am entirely confused by cousin relationships beyond "first." This chart is very helpful though it lacks the category of "kissing cousin."

Kano is a Raspberry Pi based computer system. It comes with everything you need besides an HDMI monitor. I love the keyboard with the included trackpad. At this sale price, it's probably cheaper than separately buying a Raspberry Pi, a microSD card, a case, a keyboard and pointer, a power supply, and cables. Plus, Kano's Linux OS is packed with fun goodies.

When Trevor Noah brought The Daily Show to his South African home to celebrate what would have been Nelson Mandela's 100th birthday, he stopped by his childhood neighborhood to visit with his 91-year-old grandmother. Her memories of what it was like to live under apartheid is both shocking and heartbreaking. Read the rest
