Hello, Tuesday! Nice to see you, friends! Let’s start with our tech trivia. When you type "do a barrel roll" into Google Search, what happens to your browser page? Does it … turn upside down, spin like a barrel roll, become rainbow-colored or shake from left to right? You’ll find the answer at the end!

I don't mean to frighten you, but there seems to be a disturbing trend when people sell on Facebook Marketplace, OfferUp or Craigslist. Sure, these platforms are a decent place to make cash, but scary stuff does happen.

Earlier this year, a Florida man was robbed at gunpoint when he met with a buyer for his old iPhone. The suspect was armed and demanded the guy hand over the device.

He didn't — and the suspect fired a shot into the ground and clocked him in the face with the gun. Yes, he got away with the phone.

Meeting at night is a no-no

Just last week in Oklahoma, a woman was badly injured in a Facebook Marketplace meet-up gone bad. She agreed to swap a Nintendo Switch for a laptop. Then, things took a turn. The man met her in a dark parking lot, and the woman immediately noticed the laptop wasn't what he’d shown her online. When she called him out on it, he grabbed both items and hopped back into his truck.

She reached in to take back her Switch, and he shifted into reverse, dragging her quite a while before she hit the pavement. The man was charged with assault with a deadly weapon.

Don’t give out your address

A Seattle man found a buyer for his used MacBook Pro through OfferUp. He gave the buyer his home address, and when he pulled up, the seller noticed the license plates were just dealership ad cards (a big red flag).

The buyer insisted on using CashApp and showing the laptop to his girlfriend, who was sitting in the car. When the seller refused, the buyer pulled an eight-inch knife on the man. Yeah, he got away with the laptop.

Practice safe selling

It might be your best bet to go entirely online and let a site like Amazon, Decluttr or Gazelle take your old tech gear. If you do want to sell to someone locally, do it safely:

• Meet in a public place for your exchange. Bring a friend. Libraries, police departments and municipal buildings are all safe bets. Check out police department safe-trading zones in your area.
• Stick to daylight hours. If it has to be at night, make sure your meeting place is well-lit and bring someone along.
• Ask for cash. Some people are fine with payment platforms like PayPal, Venmo or CashApp, but not me.
• Be aware of your surroundings. When the other party arrives, look at the vehicle and license plate number. Snap a pic if you can without arousing suspicion.
• Avoid giving your real phone number. If you're using Facebook Marketplace, communicate through the app. You can also set up a free burner phone number.

You know, I just bought a used time machine on Craigslist. They sure don't make them like they're going to anymore. (Get it?)

Meet Metabolic Daily, a multi-strain probiotic that improves your metabolism. But don’t just take our word for it. “I immediately felt the difference in both my body and mind and I’ve been using it every day since,” says Halle Berry, award-winning actor and Metabolic Daily fan. Berry reached out to Pendulum — the company that makes Metabolic Daily — which led to her newest role as their Chief Communications Officer.

Formulated with Akkermansia muciniphila and other next-generation strains, Metabolic Daily reduces sugar cravings, breaks down carbs more efficiently and sustains energy levels.

The result? Pendulum customer, Michelle, says it best ... "Astonishing! I am very happy and highly recommend!"

🎭 Off to a flying art: Laws are trying to keep up with artificial intelligence (AI). Case in point: AI art doesn’t get copyright protection because it’s not created by humans. That’s what a federal judge said when he ruled against Stephen Thaler, who used his Creativity Machine algorithm to create images. Expect to see this case in appeals court.

Just wing it: American Airlines is suing a website for “deception” for selling tickets with “skip-lagging,” a trick when you leave at a layover for a cheaper fare. Do this and you might get booted — like the 17-year-old who got a three-year ban last month. Airlines say it leaves open seats others could’ve used.

🔑 No keys here: Lots of people report being locked inside a Tesla after their car batteries went kaput. If it happens to you or someone you know, there should be a manual door-release lever right next to the door’s base. Find that release now in case you need it in the future.

Swiping for a paycheck: A recent survey from dating app Grindr found 25% of its users aren’t looking for love only. They’re networking for career moves and jobs. Better trade those shirtless selfies for pro headshots.

Big AI oops: An AI-penned Microsoft article listed a food bank in Ottawa, Canada, as a must-see tourist attraction — and even advised visitors to come hungry. Yikes. Microsoft took down the article, but there’s more proof we need human editors.

$4 movie tickets: Want to catch “Barbenheimer" on the big screen without breaking the bank? This Sunday is National Cinema Day, and over 3,000 theaters across the U.S. have $4 tickets. Find out which theaters are participating near you here.

Guard your EV cables: Thieves are swiping electric car chargers from public stations and private driveways. They have valuable copper inside. Be sure to park in the light, lock up your cable or charge in your garage. Warn your family and friends.

🧀 Nacho cheese: Next time you grate Parmigiano-Reggiano over your pasta, you might discover a microchip. To cut down on counterfeits, cheesemakers are implanting grain-of-sand-sized silicon chips into their expensive wheels. Don’t fret — they're food-safe.

🚍 When my son, Ian, was little, he’d watch the same things over and over. My heart goes out to these parents on round No. 418 of “Wheels on the Bus.”

Whether it’s a collectible or a used car, there’s an excellent way to determine its worth: Use eBay. Don’t waste your time scrolling through all the active listings, though. Most of those sellers are just hoping for the best.

• Search for a term.
• After getting eBay search results, go to Filter and scroll to Sold Items. Check off the box if you’re on a computer, or tap the slider if you’re using the eBay app.

Now, you’ll only see listings that actually sold to customers. This gives you a better idea of accurate prices.

And a little trivia fact to share with your friends: The very first thing sold on eBay was a broken laser pointer in 1995.

Rim shot!

The answer: Typing "do a barrel roll" into Google Search causes the results page to spin around like a barrel roll in an airplane maneuver. It’s like this: You take a barrel, put it on a hill and let it fill with air. You could say that this is a barrel of laughs. You know why? Because it’s hilarious.
