These amazing science fair projects make your potato battery look prehistoric

science fair projects
Thanks in part to the fact that information is so readily available online, kids today are smarter than ever before. Sure, quick access to distractions like Snapchat and Angry Birds aren’t helping, but games and tools like Minecraft, Tynker, and Parrot are letting kids use their creativity to explore problem solving in ways no other generation has.

But their prowess for problem solving doesn’t stop at the computer. The projects kids make at science fairs nowadays easily beat out the smelly potato batteries and homemade volcanoes you remember making when you were their age. From flying robots to a Lego spacecraft, these are some of our favorite science fair projects.

Lego Loki Launcher

Sisters Kimberly and Rebecca Yeung had one simple mission: Launch their cat into space. Kimberly and Rebecca were only nine and eleven-years-old at the time, but they were able to successfully launch their spacecraft 78,000 feet into the air with a GoPro and tracking devices attached so they could analyze the data and take in the view from (near) space. Lego Loki Launcher was able to take flight with a weather balloon, and once it popped at its peak, a parachute deployed and the craft came back down a mile of its launch site.

Their project caught the attention of President Obama, and it was featured at the final White House Science Fair in 2016. And don’t worry, they didn’t actually send their cat into space, just a picture of him, along with a lego R2D2.

Wearable sensors for Alzheimer patients

Kenneth Shinozuka’s grandpa is one of more than 5 million Americans who suffer from Alzheimer’s. Even though his grandpa lives with him and his family, it was still difficult to notice when he would get out of his bed and wander around, and potentially hurt himself.

So at 15, Shinozuka did something about it. He built a slim sensor for his grandpa to wear on his heel, and every time he stepped out of bed his family would be alerted on their phones via the app he developed. Shinozuka’s work earned him honors at the Google Science Fair, a $50,000 scholarship, and the Scientific American Science in Action Award.

Robots that fly and avoid danger

Fruit flies suck, but Mihir Garimella loves them. Probably because they helped inspire his flying robot design and win him top honors in the 13-14 age category at the Google Science Fair in 2014.

After months of coding and tinkering with sensors, Garimella developed a lightweight sensor module and attached it to a small drone body that he built. Just like a fly, Garimella’s robot can avoid dangers, and he’s hoping that future improvements to his design will allow his robot to be used for rescue missions in unpredictable environments like collapsed buildings.

A robot to clean New York’s subways

High school friends Amro Halwah, Stephen Mwingria, and Si Ya Ni, used to always be late to class.

They’d always be late because they had to take the New York subway to get to school, and the system was always delayed because of rubbish fires in the tunnels. The three of them decided enough was enough, and with the help of a grant from MIT,  they built a 100-pound robot that moves on rails and vacuums up debris in the tunnels, so that no more fires could ignite. Their robot isn’t used by subways yet, but it was featured at the White House Science Fair.

Help ambulances move through traffic

Traffic is a nuisance to us, but for ambulances it’s life or death. Viney Kumar realized this after he visited India when he was 14 years old and saw an ambulance stuck in traffic for nearly an hour. It upset Kumar that there wasn’t a better way for ambulances to travel, so he decided to do something about it.

When he went back home to Australia, he started work on a transmitter to alert drivers of when an ambulance is nearby. By installing his transmitter in an ambulance, drivers with Kumar’s app will be alerted when an emergency vehicle is within 800 and 500 meters. This gives drivers 67 seconds to respond to an ambulance, which is way better than the current average of 14 seconds. Kumar’s amazing project won at the Google Science Fair for his age group, and he’s hoping that companies like Google and Apple will consider putting his technology in the dashboards they’re building for cars.

CES 2023: HD Hyundai’s Avikus is an A.I. for autonomous boat and marine navigation
Demonstration of NeuBoat level 2 autonomous navigation system at the Fort Lauderdale International Boat Show

This content was produced in partnership with HD Hyundai.
Autonomous vehicle navigation technology is certainly nothing new and has been in the works for the better part of a decade at this point. But one of the most common forms we see and hear about is the type used to control steering in road-based vehicles. That's not the only place where technology can make a huge difference. Autonomous driving systems can offer incredible benefits to boats and marine vehicles, too, which is precisely why HD Hyundai has unveiled its Avikus AI technology -- for marine and watercraft vehicles.

More recently, HD Hyundai participated in the Fort Lauderdale International Boat Show, to demo its NeuBoat level 2 autonomous navigation system for recreational boats. The name mashes together the words "neuron" and "boat" and is quite fitting since the Avikus' A.I. navigation tech is a core component of the solution, it will handle self-recognition, real-time decisions, and controls when on the water. Of course, there are a lot of things happening behind the scenes with HD Hyundai's autonomous navigation solution, which we'll dive into below -- HD Hyundai will also be introducing more about the tech at CES 2023.

There's a scene in Mission Impossible 3 that you might recall. In it, our hero Ethan Hunt (Tom Cruise) tackles the movie's villain, holds him at gunpoint, and forces him to read a bizarre series of sentences aloud.

"The pleasure of Busby's company is what I most enjoy," he reluctantly reads. "He put a tack on Miss Yancy's chair, and she called him a horrible boy. At the end of the month, he was flinging two kittens across the width of the room ..."
