Avocado farmer explains secret why you can't grow Hass avocado trees from Hass seeds
Did you know this?

An avocado tree farmer explains the science of Hass avocados
Have you ever seen anyone put an avocado pit in water to grow an avocado tree?
I've seen lots of people try, but only a few succeed. My mom has a tiny avocado tree growing in her living room that she managed to grow from the pit of a Hass avocado she ate. It's small but thriving, and I've often wondered if it will ever grow actual avocados.
As it turns out, it could—but they won't be Hass avocados.
Wait, huh?
In a wow-that's-an-interesting-factoid-I-never-knew-before YouTube video, an avocado farmer explains why a Hass avocado seed doesn't grow into a Hass avocado tree. Avocados, apparently, are not "true to seed" plants, meaning if you plant the seed, you'll end up with a different variety of the fruit the seed came from. Apples are the same—if you plant a Fuji apple seed, you will not get a Fuji apple tree.
In fact, chances are really, really high that you'll get an avocado or an apple that tastes terrible if you try to grow it from the seed of an existing fruit.
The guy from Sleepy Lizard Avocado Farm, Tom Siddons, explains how it all works using an analogy with candy flavors. This is the genetics lesson we all needed in school when we were trying to figure out Punnett squares, and he explains it all so clearly.
Incredible how nature works, and so amazing what human beings have been able to figure out over millennia of agricultural advancements.
So how do you get a Hass avocado tree if not from a Hass avocado seed? As Siddons explains in the video, you can plant the pit and start to grow the tree, but if you want Hass avocados you have to graft a branch of a Hass avocado tree onto the stem of the tree you're growing.
Or, you can just buy a baby Hass avocado tree that's already been grafted, which is probably a heck of a lot easier than doing it yourself.
So, go ahead and sprout that seed in water and grow yourself a pretty avocado plant if you'd like. Just don't expect any yummy avocados from it since your chances are about 1 in 10,000 that it'll happen.
Thanks for the fascinating lesson, avocado guy!

An Irish woman went to the doctor for a routine eye exam. She left with bright neon green eyes.
It's not easy seeing green.
Did she get superpowers?
Going to the eye doctor can be a hassle and a pain. It's not just the routine issues and inconveniences that come along when making a doctor appointment, but sometimes the various devices being used to check your eyes' health feel invasive and uncomfortable. But at least at the end of the appointment, most of us don't look like we're turning into The Incredible Hulk. That wasn't the case for one Irish woman.
Photographer Margerita B. Wargola was just going in for a routine eye exam at the hospital but ended up leaving with her eyes a shocking, bright neon green.
At the doctor's office, the nurse practitioner was prepping Wargola for a test with a machine that Wargola had experienced before. Before the test started, Wargola presumed the nurse had dropped some saline into her eyes, as they were feeling dry. After she blinked, everything went yellow.
Wargola and the nurse initially panicked. Neither knew what was going on as Wargola suddenly had yellow vision and radioactive-looking green eyes. After the initial shock, both realized the issue: the nurse forgot to ask Wargola to remove her contact lenses before putting contrast drops in her eyes for the exam. Wargola and the nurse quickly removed the lenses from her eyes and washed them thoroughly with saline. Fortunately, Wargola's eyes were unharmed. Unfortunately, her contacts were permanently stained and she didn't bring a spare pair.

Since she has poor vision, Wargola was forced to drive herself home after the eye exam wearing the neon-green contact lenses that make her look like a member of the Green Lantern Corps. She couldn't help but laugh at her predicament and recorded a video explaining it all on social media. Since then, her video has sparked a couple Reddit threads and collected a bunch of comments on Instagram:
“But the REAL question is: do you now have X-Ray vision?”
“You can just say you're a superhero.”
“I would make a few stops on the way home just to freak some people out!”
“I would have lived it up! Grab a coffee, do grocery shopping, walk around a shopping center.”
“This one would pair well with that girl who ate something with turmeric with her invisalign on and walked around Paris smiling at people with seemingly BRIGHT YELLOW TEETH.”
“I would save those for fancy special occasions! WOW!”
“Every time I'd stop I'd turn slowly and stare at the person in the car next to me.”
“Keep them. Tell people what to do. They’ll do your bidding.”
In a follow-up Instagram video, Wargola showed her followers that she was safe at home with normal eyes, showing that the damaged contact lenses were so stained that they turned the saline solution in her contacts case into a bright Gatorade yellow. She wasn't mad at the nurse and, in fact, plans on keeping the lenses to wear on St. Patrick's Day or some other special occasion.
While no harm was done and a good laugh was had, it's still best for doctors, nurses, and patients alike to double-check and ask or tell if contact lenses are being worn before each eye test. If not, there might be more than ultra-green eyes to worry about.
