One Skate In Front of the Other

We know the wheel was invented by a bunch of cavemen thousands of years ago, but that wasn’t the end of it. It took centuries for people to see all the objects that could work – or work better – with wheels attached, resulting in all the cars, trucks, pulleys, and all our other machinery that uses spinny round things. Roller skates just showed up in the last couple of centuries: one version came out in 1760 but folks didn’t take to it, probably because they kept falling down. Then on this day in 1869, apparently Isaac Hodgson filed a patent for his roller skate, and the rest is history. Now we have sports played entirely on skates, like roller hockey, speed skating and roller derby. All of these go faster on wheels, but are a lot harder than playing on your regular old feet.

Real-Life Treasure Hunt

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.

A Day for Wishes and Tricks

It’s St. Patrick’s Day, that Irish holiday when we wear green clothes, eat green food, and maybe score some “luck of the Irish” for ourselves. There are leprechauns, those funny elf-like fellows from Irish fairy tales who are only as tall as kids, but have big magical powers. Supposedly they keep all their coins in a pot of gold at the end of a rainbow, which would be a great thing to find. It’s even better to find the leprechaun himself, because if you capture him he’ll grant you 3 wishes. Another Irish symbol is the shamrock, or 3-leaf clover, because long ago people in Ireland believed that carrying a clover kept you safe from evil spirits. It’s still a sign of good luck today, and 4-leaf clovers are even better luck. Who knows, maybe today you’ll find a leprechaun or a clover – or at the least, you’ll get to eat a green pretzel.

On the Other Hand…

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.
