These amazing science fair projects make your potato battery look prehistoric

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.

Digital Trends’ Tech For Change CES 2023 Awards
Digital Trends CES 2023 Tech For Change Award Winners Feature

CES is more than just a neon-drenched show-and-tell session for the world’s biggest tech manufacturers. More and more, it’s also a place where companies showcase innovations that could truly make the world a better place — and at CES 2023, this type of tech was on full display. We saw everything from accessibility-minded PS5 controllers to pedal-powered smart desks. But of all the amazing innovations on display this year, these three impressed us the most:

Samsung's Relumino Mode
Across the globe, roughly 300 million people suffer from moderate to severe vision loss, and generally speaking, most TVs don’t take that into account. So in an effort to make television more accessible and enjoyable for those millions of people suffering from impaired vision, Samsung is adding a new picture mode to many of its new TVs.
[CES 2023] Relumino Mode: Innovation for every need | Samsung
Relumino Mode, as it’s called, works by adding a bunch of different visual filters to the picture simultaneously. Outlines of people and objects on screen are highlighted, the contrast and brightness of the overall picture are cranked up, and extra sharpness is applied to everything. The resulting video would likely look strange to people with normal vision, but for folks with low vision, it should look clearer and closer to "normal" than it otherwise would.
Excitingly, since Relumino Mode is ultimately just a clever software trick, this technology could theoretically be pushed out via a software update and installed on millions of existing Samsung TVs -- not just new and recently purchased ones.

AI turned Breaking Bad into an anime — and it’s terrifying
Split image of Breaking Bad anime characters.

These days, it seems like there's nothing AI programs can't do. Thanks to advancements in artificial intelligence, deepfakes have done digital "face-offs" with Hollywood celebrities in films and TV shows, VFX artists can de-age actors almost instantly, and ChatGPT has learned how to write big-budget screenplays in the blink of an eye. Pretty soon, AI will probably decide who wins at the Oscars.

Within the past year, AI has also been used to generate beautiful works of art in seconds, creating a viral new trend and causing a boon for fan artists everywhere. TikTok user @cyborgism recently broke the internet by posting a clip featuring many AI-generated pictures of Breaking Bad. The theme here is that the characters are depicted as anime characters straight out of the 1980s, and the result is concerning to say the least. Depending on your viewpoint, Breaking Bad AI (my unofficial name for it) shows how technology can either threaten the integrity of original works of art or nurture artistic expression.
What if AI created Breaking Bad as a 1980s anime?
Playing over Metro Boomin's rap remix of the famous "I am the one who knocks" monologue, the video features images of the cast that range from shockingly realistic to full-on exaggerated. The clip currently has over 65,000 likes on TikTok alone, and many other users have shared their thoughts on the art. One user wrote, "Regardless of the repercussions on the entertainment industry, I can't wait for AI to be advanced enough to animate the whole show like this."

4 simple pieces of tech that helped me run my first marathon

The fitness world is littered with opportunities to buy tech aimed at enhancing your physical performance. No matter your sport of choice or personal goals, there's a deep rabbit hole you can go down. It'll cost plenty of money, but the gains can be marginal -- and can honestly just be a distraction from what you should actually be focused on. Running is certainly susceptible to this.

A few months ago, I ran my first-ever marathon. It was an incredible accomplishment I had no idea I'd ever be able to reach, and it's now going to be the first of many I run in my lifetime. And despite my deep-rooted history in tech, and the endless opportunities for being baited into gearing myself up with every last product to help me get through the marathon, I went with a rather simple approach.
