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.
