Ever heard of a dynamite tree? It's a tree built to kill.

The planet never ceases to provide things that leave us in awe.

sandbox tree, deadly trees, exploding fruit

Who's stringing lights on this guy for the holidays?

Ah, trees. One of Mother Nature’s most majestic creations. Always glorious sights to behold, with their bountiful blooms, luscious leaves and poisonous fruit bombs…

Wait, what?

You read that correctly. The sandbox tree, also known as the monkey no-climb or dynamite tree, lives up to all of its nicknames. It might not hold the official record for being the “most deadly tree in the world,” but it certainly comes close.

A video posted to YouTube by Animalogic gives a fun deep dive on the sandbox tree and all the ways in which it “chooses violence.” Reader beware: This might cause trust issues with other trees. Suddenly you might find yourself wondering what that birch in your front yard’s real intentions are.

First off, let’s talk about those fruit bombs.


The sandbox tree’s official name references the small pumpkin-like fruit it bears. Up until the mid-1800s, when sand was the primary tool for blotting ink, these small gourds made a perfect container for sand and therefore were a standard desk item until they were replaced with blotting paper, Animalogic explained.

But when not being harvested as desk ornaments, these fruits can act as seed explosives. Though this is more of a reproductive strategy than a defensive attack (aiming to get the seeds as far away from the parent plant as possible), humans and animals caught in the crossfire can still be badly hurt by a relentless seed onslaught.

Luckily these seed grenades are fairly predictable and therefore avoidable. They don’t explode at night or when the air is damp, as they need heat and dryness to be ignited. When temperatures are high, however, the fruit will lose more than half of its moisture—becoming so dry each of the 15 sections will violently split away from each other … sort of like distant cousins at an outdoor family reunion. If that happens, look out!

Next, we have stabbing bark.

Yep, from top to bottom, the sandbox tree is densely covered in needle sharp, knife-like points. Hence, monkey no-climb (and hopefully nothing else tries to climb it either). No wonder Animalogic likened it to a “medieval torture device.”

When all else fails, the sandbox tree relies on a weapon that’s withstood the test of time—poison.

Remember those fruit bombs? Well, even if they don’t explode and kill you, just one bite could result in violent cramps, vomiting and diarrhea. OK, so maybe it’s not death … but it ain’t great.

The sandbox tree’s thick, red sap it secretes is also toxic, creating a skin rash on contact, not to mention temporary blindness if it gets into your eye. Indigenous peoples would dip their darts into this sap for hunting and warfare. On the plus side, certain parts of the plant can allegedly be used to treat stomach issues, eczema, rheumatoid arthritis and intestinal worms. Please, please don’t try this at home.

Much like Audrey II in “Little Shop of Horrors,” this tree seems hellbent on world domination. Because of its explosive and efficient seed dispersing system, the species is now considered invasive in East Africa. Ironically, the trees were consciously planted there for shade.

One person joked in the video’s comments, “okay, who thought the poisonous, explosive, thorn-covered tree would be the best option to import for shade?” A fair question!

The sandbox tree might be a tad toxic, deadly, intrusive and insidious, but it’s still pretty cool to learn about. The planet never ceases to provide things that leave us in awe … and in this case, terrified.

And special kudos to Animalogic for providing entertaining and educational videos. You might have given us some nightmare fuel, but we love it.

Things new parents think they need but don't.

There's nothing like preparing for a new baby. The excitement and anticipation take hold and before you know what's happening, your baby registry is five pages long full of things you've probably never heard of. I've been there before, and now, four kids later, I can tell you with absolute certainty that there are tons of things you actually don't need. It's easy to get carried away when everything is so tiny and cute, especially 'cause marketing around baby stuff is bananas. The following offers some alternative items to the ones you'll likely only use a limited number of times before practicality takes over.

TikTok user Absolutely Lauren catches an online scammer.

There was a massive jump in credit card fraud in America in 2021 due to the pandemic. According to CNET, fraud involving credit cards jumped 69% from 2020 to 2021, affecting 13 million Americans and costing $9 billion.

In a world where online transactions are part of everyday life, it’s hard to completely protect your information. But, by staying vigilant and monitoring your accounts you can report fraud before it gets out of hand.

A TikTok user by the name of Lauren (@absolutelylauren) from San Diego, California, got a notification that there was a $135 charge on her card at Olaplex’s online store that she hadn’t made. Olaplex sells products that repair excessively damaged hair. Before reporting the charge to her credit card company she asked her family members if they used her card by mistake.

“I don’t wanna shut my card down if it’s just my mom ordering some shampoo,” Lauren said in the video. “Definitely not my two younger brothers, they’ve got good hair but they don’t color it.”

Man breaks down how living in an all-inclusive resort is cheaper than his average apartment

"I just might find myself on a beach somewhere sucking down cocktails and WHAT OF IT."

Are resorts the new retirement homes?

Don’t know if you heard, but the cost of living is pretty high these days. Prices for groceries, restaurants, gas, and other necessary items just to, you know, live in the world, reaching an all time high is already making what used to be a decent wage barely enough to get by.

And let’s not forget the biggest financial whammy of all: rent prices. According to Zillow, the average rent price in the US was $1,958 ( recorded in January 2024). That a whopping 29.4% price jump since pre-pandemic times. And of course, that not even taking larger, more expensive cities into account.


It’s enough to make you wonder: “Is it actually cheaper to just live in an all-inclusive resort at this point?”

Terrified, emaciated dog comes to life as volunteer sits with him for human connection

He tries making himself so small in the kennel until he realizes he's safe.

Terrified dog transforms after human sits with him.

There's something about dogs that makes people just want to cuddle them. They have some of the sweetest faces with big curious eyes that make them almost look cartoonish at times. But not all dogs get humans that want to snuggle up with them on cold nights; some dogs are neglected or abandoned. That's where animal shelters come in, and they work diligently to take care of any medical needs and find these animals loving homes.

Volunteers are essential to animal shelters running effectively to fill in the gaps employees may not have time for. Rocky Kanaka has been volunteering to sit with dogs to provide comfort. Recently he uploaded a video of an extremely emaciated Vizsla mix that was doing his best to make himself as small as possible in the corner of the kennel.

Kanaka immediately wanted to help him adjust so he would feel comfortable enough to eat and eventually get adopted. The dog appeared scared of his new location and had actually rubbed his nose raw from anxiety, but everything changed when Kanaka came along.
