I had a plan. I even publicly announced it (though that was never my intention). I had been saving old hard drives with the intention of extracting the super powerful magnets from them. I was looking into rain barrels. The place we just moved into has a large roof that funnels all the water down into one drain.

It would have been a simple matter to use the magnets to collect all the little bits of magnetic stuff that falls on the house over time, from the sky. And, since most of these bits of magnetic stuff are iron meteorites, I’d be able to collect a zillion meteorites every year! Bwa ha ha ha!!!

Math Mystery Book That Is Bilingual

You can solve mysteries with math, and you can do it in either English or Spanish, with One Minute Mysteries – Misterios de un Minuto: Short Mysteries You Solve With Math! – ¡Misterios Cortos que Resuelves con Matemáticas!, by Yoder and Yoder.

The original version of this book was all English, and was a best seller. This new version obviously gives you mucho mucho mas and math to boot.

The One Minute Mysteries series is well known and widely loved, and is recommended by the NSTA.

Have a notebook or a pile of blank paper and some writing instruments handy because you will need them to work out some of these problems.

This is for kids age 10-14, and is a well written, well constructed, well printed resource. I strongly recommend it if your family has young ones around that age, regardless of their math level. Also check out One Minute Mysteries: 65 Short Mysteries You Solve With Science! and One-Minute Mysteries and Brain Teasers: Good Clean Puzzles for Kids of All Ages.
