Sometimes you look at your everyday life and decide you need a change – a big change. And one way to get that is to repaint your bedroom. Lots of colors, lots of eye-hurting patterns – something that will make a statement.
If you could repaint your room, and could go as crazy as you wanted, what colors would you use? Of course, the fancier you get, the more carefully you have to plan.
When we drive on the road, we can’t all just go every which way. We have to stay on one side, and wait our turn where roads cross. Stop signs help, but really busy crossings need traffic lights. The traffic light, that cute red, yellow and green trio, was patented (made official as an invention) on this day in 1923. Actually, the very first electric traffic light was invented in 1912 by Lester Wire, a policeman in Utah fed up with all the traffic; you can imagine, after hundreds of years of slow horse-drawn carriages, what it was like to have this speedy, loud thing called a car suddenly show up. So Wire borrowed the idea of railroad signals to make a traffic light, which had just red and green for stop and go. Then in 1920, Detroit cop William Potts built one with 3 colors (red, orange and green). As you see here, people have tried other designs, like this funny dial one from Australia, but the three-color light is what keeps most of us from crashing into each other today.
Waffles are yummy no matter what shape they come in. But it must be a lot of fun to eat keyboard-shaped waffles – especially when there are so many square holes to catch the syrup! Read on to eat up the math in this funky invention.
Bedtime Math fan Arun W. just asked us a question we’d never thought about: how many Cheerios are in a box of Cheerios? Read on to find out, and add up the big fun in these little Os!
The New Year is a popular time to start “resolutions,” or promises to become a better person. But just how long does it take for that promise to stick? Read on to do the New Year’s math in resolutions!
You might stay up extra late on New Year’s Eve to celebrate it turning the next year. But if you do, you’re usually extra tired the next day, which causes lots of yawning. Read on to do the math on how yawns stack up when they go from one person to another – and even to your dog!
Have you ever wanted to live in a fairy-tale castle? This is a real castle called the Swallow’s Nest, on the south coast of Crimea, and would make anyone feel like a king or queen. Read on to do the math on this real-life castle!
Have you ever seen one thing suddenly look like something else, like an electrical outlet that looks like a smiley face? Our brains like to see patterns, and...
Houses and hotels are usually made out of hard bricks, wood, and materials like that. But the Lego Hotel in California decided to make its hotel out of Lego – or at least make it look like it’s made from Lego pieces. Read on to discover the fun and numbers in this one-of-a-kind building!
It’s fun to get a goody bag after going to a party. And just imagine if that goody bag is actually filled with water…and a new pet fish! Read on to find out more about this event that actually happened at Bedtime Math, and see just how much math those new fish pet-owners did to keep their swimming friends happy.
