Answer:

We humans are a creative bunch. We just keep coming up with awesome inventions and gadgets that make life easier — or just more interesting!

1. You have to brush your teeth. So why not get it done as quickly as possible? A new gadget called the Unico Smartbrush will help you do just that. It cleans your teeth in three seconds flat! And all you have to do is place it in your mouth. The smartbrush is basically a mouth guard that’s packed with rotating electric toothbrush heads. Toothpaste automatically squirts onto each brush, and then the brushes get busy cleaning every surface of your teeth. The toothbrush even sprays out mouthwash from tiny nozzles to make sure your tongue gets cleaned, too. Sounds like something to smile about!
2. a robotic falcon that has just begun some serious work at the Edmonton International Airport. The robo-bird chases away real birds from the airport. It seems that birds are a hazard to planes as they’re taking off and landing. So it’s robo-bird to the rescue! A flock of these fake falcons are flown around the airport to scare off real birds. Here’s how it works: The robotic birds look like real falcons. They even flap their wings and fly just like them so real birds think the falcons are a predator. They get spooked and fly off. And when the birds stay away, it makes the airport a safer place.
3. the perfect invention for anyone who can’t get enough of practicing their free throw. The Dr. Dish iC3 Basketball Shot Trainer fits over any basketball net. It catches a basketball when you toss it to the net and sends it down to a holder below. That way, you can grab the ball quickly from the holder and take another shot. The b-ball gadget means you can spend your time practicing those shots over and over again rather than chasing down the basketball each time it rolls away. Nothing but net!
4. We all know how important it is to recycle, but sometimes waste and recycling aren’t always separated properly. This is a big problem with public bins where garbage and recycling often get thrown in together by people who aren’t paying close attention. An invention called the Bin-e hopes to help fix that. This waste bin automatically sorts items into the correct bin, by figuring out what’s garbage and what’s recycling. To do this, the Bin-e has special sensors and cameras. They help the bin examine items and then each item is placed in its proper container. This is one gadget that definitely puts the planet first!
