You probably don’t think about toilet paper too often – until it runs out. Well, if you get the new ‘Forever Roll’ of toilet paper, you’ll think about...
Lots of kids like to draw for fun, whether with crayons or markers, fingerpaint or melted chocolate. The fun doesn’t have to end when you grow up, though. If you’re great at drawing, you can get paid to draw as your job! Look at Jim Paillot, who draws the pictures or “illustrations” in the Bedtime Math books. He gets to draw all day! He has drawn not only our books, but also dozens of My Weird School books as well as others. By the way, some drawings are more work than others. Spot art of just one animal or person. like the girl here from Bedtime Math 2, doesn’t take long to draw, but full page “illos” have to fill the whole page with color and scenery and more. When you add up all those books and the drawings on each page, you see quickly that drawing is not just great play, but hard work, too.
Today is April Fools’ Day, the day we play pranks on people, like freezing the milk in their cereal, to make them look like fools. Click “Read More” to do the April Fools’ Day math…and maybe get a few ideas for tricks!
You never know what’s buried in your backyard, and for one California couple, their yard held real treasure. When they saw a can sticking out of the ground, they dug it out and ended up finding eight cans filled with 1,427 gold coins! The mix of $5 coins, $10 coins and $20 coins was minted (made) between 1847 and 1894, back when Americans used coins for those amounts. If you add up all those $10s and $20s, the coins have a total face value of almost $28,000. But they are worth far more than that, because the older a coin, the fewer of that coin we still have, and so the more that coin is worth. One of the coins is worth over $1 million all by itself, and all together the collection is estimated at $10 million. So what do you do when you suddenly find $10 million of coins in your backyard? Bury them again, of course! But just to be safe, they picked a new spot.

It’s amazing what you can do with paint. People who paint pictures that look really real can create a whole new kind of magic. These crazy buses are a great example of that. In the top picture, the back of a bus is painted to look like it has a battery compartment. In the second, someone painted around the wheels to make them look like two eyes. And in the third, the stretchy part of the bus looks like the bendy part of a toothbrush. Buses are a good 40-50 feet long, though, so these eyes and batteries and brushes are way, way bigger than real ones. How much bigger are they?
We all like different music from each other. You and your friend might like some of the same songs, but not every song, and your parents definitely don’t like all the same songs as you. So what about cows: do cows all like the same music? And is there one kind they like best? Scientists studied this a few years ago by playing different songs for cows to see if the cows made more milk during certain songs. They found that when listening to songs with fewer than 100 beats a minute – maybe about 1 beat per second – the cows gave 3% more milk: in the time the farmers normally got 100 cups from them, they now got an extra 3 cups. Even though people have been studying this since the 1930’s, no one’s sure whether music really makes cows make more milk – or more importantly, whether the milk tastes better.
So March 20 is pretty special, and not just because it’s the 79th day of the year. In most years March 20 is the start of spring, also called the vernal equinox. Equinox comes from the Latin words for “equal night,” because on this day Earth is tilted perfectly so every spot on the planet has 12 hours of both day and night. Because of that perfect tilt, people try to balance an egg on end at the exact moment of the equinox. Does that actually work? It does – because you can balance an egg any time! And, as noted in this week’s family activity on our Add It Up blog, eggs are also incredibly strong. While they break easily if they fall sideways onto the floor, they hold up surprisingly well when you press in on them. Take a couple of small plastic cups, stack your egg between them as shown here, and try balancing lots of heavy objects…you’ll find your egg can stand up to a lot.
We all get Happy Birthday wishes and cards from your friends, family, maybe even your dentist… but what about complete strangers? Well, one man named Chris Ferry is...
Most people are right-handed, which means they use their right hand to write and generally feel stronger using their right side. However, there are people out there who are left-handed, which means that they write with their left hand, and probably pour drinks, brush their hair, and do lots of other things lefty. In the old days, everyone thought left-handed people were a threat to society. But don’t worry, now that we have Google to look up all this stuff, we know that being lefty isn’t bad at all. In fact, it might mean you’re better at certain things, like music and math. You will, however, have to get a different-shaped glove to play catch.
