They gave him $20,000 to build a car out of Legos. Here's what he came up with.

The fact that it's made out of 500,000 Legos isn't even the best thing about it.

Inventor Raul Oaida wanted to build something that would capture people's imaginations.

Ultimately, he decided to build a car. You might be thinking, What's so imaginative about a car? For starters, Oaida's car is made out of half a million Legos.


Now, the fact that it's a Lego car is pretty awesome, but that's not even the best thing about it.

It's that it actually drives — and it's emission-free.

Oaida was able to achieve it using a technology that not too many folks know about: compressed-air engines.

"We wanted to bring attention to air-powered cars because most people have no idea that this stuff is actually out there."
— Raul Oaida

He pointed to a model by Peugeot that already uses compressed-air technology.

Peugeot's hybrid air vehicles are set to hit the market in 2016.

Compressed-air vehicles could dramatically reduce city drivers' need for gasoline and, in turn, the greenhouse gases they release into the atmosphere.

Air-powered cars have a ways to go before they replace our gas guzzlers, but it's worth a shot.

According to automotive writer Christopher DeMorro, "The search for an alternative fuel source other than oil should leave no idea untested."

And what better way to test air-powered cars than to get more people driving them?

The video above closes with the interviewer asking Oaida why he builds this stuff. I really like his answer, because it can go for anything we believe is worth doing, including breaking our reliance on fossil fuels:

"It's about the willingness to do it."
— Raul Oaida

Sometimes the smallest gesture can turn your entire day around. You find a $5 bill in the pockets of your jeans. There's no traffic on the way home from work. Or by some divine intervention, you get 11 chicken McNuggets in your 10-piece box.

Of course, if you've ever had such a blessing, you know your first thought is, "Must be some sort of mistake."

But do you return the extra McNugget? Nope. You don't even feel an ounce of guilt for it. You dunk it in barbecue sauce and relish it like a gift from the gods.

A former McDonald's employee in Edmonton, Canada let the world know that sometimes an extra McNugget is not a mistake and he's become a viral hero.

When Iowa Valley Junior-Senior High School principal Janet Behrens observed her students in the cafeteria, she was dismayed to see that they spent more time looking down at their phones than they did looking at and interacting with each other. So last year, she implemented a new policy that's having a big impact.

They say that kids say the darnedest things, and seriously, they do. Anyone who has spent any significant amount of time with young children knows that sometimes the things they say can blow your mind.

Since teachers spend more time around little kids than anyone else, they are particularly privy to their profound and hilarious thoughts. That's why NYC kindergarten teacher Alyssa Cowit started collecting kid quotes from teachers around the country and sharing them on her Instagram account, Live from Snack Time, as well as her websiteand other social media channels.

Earlier this month, a beluga whale caught the world's attention by playing fetch with a rugby ball thrown by South African researchers off the waters of Norway.

The adorable video has been watched over 20 million times, promoting people across the globe to wonder how the whale became so comfortable around humans.

It's believed that the whale, known as Hvaldimir, was at some point, trained by the Russian military and was either released or escaped.
