The Science of Scabs

every kid's life

Scabs - Nature's Band-Aid

Scabs are nature's Band-Aid. They start to form less than 10 seconds after you cut yourself. Chemical proteins react with special blood cells called platelets, which cause the blood to get sticky and clump together. This forms a clot that plugs up the cut to stop the bleeding. Once you've clotted, 16 different chemicals work together to dry out the clot and form a scab. The scab keeps out germs while the cells underneath make new skin.

Scabs - White Blood Cells Chow-Down

White blood cells, which are the cells in charge of fighting off disease, arrive on the scene and chow down on any germs that sneak past the scab, as well as some of your dead blood and skin cells. Yum.

Scabs - That Icky Yellow Stuff

Piles of living and dead germs and cells form pus, which cause some swelling and puffiness around your wound.

Scabs - Don't Pick A Scab!

I know your parents always tell ya this, but they're not just grossed-out by the bloody mess you'll make. If ya pick a scab, you're messing with all the hard work your body is doing to fix itself. If you leave it alone to do its thing, a cool new kind of cell, called a macrophage arrives. They eat all the pus, dead white cells and other debris. Within a week or two, the scab should fall off all by itself.

Scabs - Did U Know?
  • Watch out! Vampire bats have chemicals in their spit that prevent scabs from forming. This makes it easier for them to snack on their victim's blood. So don't get spit on by a vampire bat if you've got an open wound.
  • If you dream about scabs, it could mean that money is coming your way.

    I found the greatest riddle ever (credits to Ted-Ed), and I want to see if anyone can solve it without looking up the answer. THE RIDDLE OF THE ALIEN OVERLORDS. You and your team have crashed-landed on an ancient planet. The only way off is to appease its three alien overlords, TEE, EFF, and ARR, by giving them the correct artifacts. Unfortunately, you don't know who is who. From an inscription, you learn that you may ask three yes or no questions, each addresses to any one lord. Tee's answers are always true. Eff's answers are always false.  And Arr's answers are random. But, there's a problem. You've deciphered the language enough to ask any question, but you don't know which of the two words 'ozo' and 'ulu' means yes, and which means no. How can you still figure out which alien is which?

    Fear: The Emotion of Death   You can't see me, But I'm there. I'm in your tears, I'm everywhere. I stalk you in your shadow, So stealthy and no slack. I'm made of dark matter, You better watch your back. You can hear me, I'm your beating heart. Inside is emptiness, Tearing you apart. You shiver and shake, At the sound of my name. I engulf you, drown you, Surround you with shame.   I've seen destruction, More than anyone. I'm darker than, The world with no sun. The agony arises, There's so much red. Most of it coming, From the dead. I become your shadow, I'm a terrible sight. And when you see me, You're frozen with fright. I'll grab you by your neck, You'll be thrashing around. You're crying, shrieking, Until there's no sound.   I feel so sad, So empty, so. . . Alone. So you'll feel the same, You'll be on your own. And as long as you are with me, At the point of no return. You will go crazy. You'll crash and burn.   Then you understand, With your slowing of breath. That I am Fear, The Emotion of Death.
