Mind Blowing Fact About Atoms!

This is an image of the Atlantic ocean which is huge. Now in your head imagine it being measured in teaspoons. That would be a very big number. Did you know that one teaspoon of water has more atoms than there are teaspoons in the Atlantic ocean? In one teaspoon there are 200,000,000,000,000,000,000,000 water molecules, and each of these is made of three atoms. If you lined all of these atoms end to end you would get 50 billion km which is 10 times the width of our solar system.

How does smog affect your vision?

If you've ever had  smoke blown in your eyes

you know it can dry out your eyes and

it makes you very irritated. It's something

you generally want to avoid smog. If you

hadn't known already by the 12,000 plus

times we blink on average a day, we blink

because our eyes need moisture almost

constantly. Smog is something that causes

ours to get very irritated and can, if long 

enough, cause some vision problems.

In Beijing, China they have one of the highest

smog pollution rates in the world and they have

many people who have medical problems from

this pollution. Imagine smoke getting blown in

your eyes right now, then Imagine living in Beijing

and having that same feeling frequently. Doesn't feel

good does it? Well smog isn't good for your eyes 

and you should stay away from it as much as possible.

Grafting like a pro | EDM

Grafting is the act of taking off a limb off a tree/plant and taping it on on another tree/plant of the same family to have more than one fruit/vegetable growing on the same plant. In other words you put the tissues of two plants together to make it grow more stuff. This is a video of Anya and i doing rad stuff in our grafting adventure. If you look far back on the science blog you can see a post on a tree that bears more than 40 fruits.
