How Rubber Bands are made

The making of a rubber band starts with a big block of natural rubber. The blocks are made out of the sap or resin from a rubber tree.  Natural rubber has more stretchy-ness than synthetic rubber, so that’s why they use it for rubber-bands.  Rubber processing oil, dye, and a few of the rubber blocks are all stuck in a big mixer/kneader machine, and they get all mixed up into big globs of “rubber dough”.  Then it is put into big rollers that make it into a big sheet.  At this time, sulfur and a few other things that help the rubber be more elasticy are added.  The rubber is then processed into small enough logs to put in the extruder which mixes it with talcum powder, and makes it into a tube, by pumping air into the middle.  Eventually these tubes are put onto long poles that are essentially molds to keep them the right diameter during the curing process.  The talcum powder helps keep the rubber from sticking to the poles.  Then, the poles with the rubber on them are put into a steam oven to cure and become more elastic.  Afterwards, the rubber is taken off of the tubes, rinsed, and then cut into rubber bands.  Now they are ready to be packed up into bags and sold!

How matches are made

Today I’m going to be telling you how matches are made!

First, gelatin, potassium Chlorate, hot water, Silica granules and some other things (that help the matches burn better) are all mixed together, then some red dye is added.  This is the match-head compound.  The match sticks are made of wood (obviously) but they are dipped in paraffin and ammonium phosphate.  They are loaded onto this thing that dips them in the match head mixture and let dry thoroughly.  The matches are finished, and ready to be packed up into boxes!

The Digestive System

So what would happen if you were a piece of food, and you got chewed up and swallowed?  Where would you go?  Well, first off, you would be in the person’s mouth.  You would get chewed up into a slimy, pasty, mass that would be swallowed.  Then, you go down this long tube called the Esophagus.  After going through the esophagus, you would find yourself in the digestive tract, which, essentially, is all of the organs that help digest food.  Now you are in the stomach. The stomach pours out all of this acid stuff that breaks down food even more.  by this time, the food is just molecules!  After being in the stomach for a few hours, you’d go through an opening called the Pyloric Sphincter.  It gauges how much food goes through it.This way, not too much food, and not too little food goes into the small intestine.  The small intestine is a long, winding, tube that the food molecules go through that absorbs the nutrients from the food.  Small intestines are more than 20 feet long!  Now you travel to the liver, which separates the good stuff from the waste and gross stuff.  It takes the vitamins from the food and puts them in your blood to help your body be healthy.  The Liver makes this stuff called bile also. It flows through the small intestine while you are in it, and helps break down fat and stuff.  The gallbladder keeps all of the extra bile that isn’t being used.  The pancreas is very important also. It makes a liquid that helps break protein and carbohydrates down even further.  Now, you are in the large intestine.  After going through there, you would land in the colon. It is basically the place where the waste separates into solid and liquid.  After that, the solid exits through the rectum. I think that I don’t need to explain that any further. 🙂

So, what is Photosynthesis?

Photosynthesis (photo-sin-thu-sis) is a process that plants use to make themselves food, and make us oxygen. It is a complicated name for a complicated process, so I’ll try to break it down for you.  Basically, the sun hits the plant or tree, and the plant uses some of that energy to turn water and carbon dioxide into a thing that it can “eat” and grow with.  What’s left over is a bunch of oxygen! God was a great engineer when he made the earth, because with all of the plants in the world converting yucky carbon-dioxide (what comes our of our mouth when we breath out) into wonderful, pure, oxygen, we never run out of air to breath!

 

This is so weird.

Did you know that clown fish change genders during their life?  This is what happens (yes, I know that it sounds super creepy and weird, but it happens) all clown fish are born as males, but the most dominant male chases all the other males away. His body goes through this weird thing called “protandry”, where he becomes a female.  Ok, now she lays a bunch of eggs in an anemone and chases a male into the anemone to babysit them.
If the “mom” dies then the male who was babysitting the eggs actually goes through the exact same thing that the first fish went through, and becomes a female, therefore a new “mom” to the eggs. This is super weird!  Tell me in the comments box if you already knew this!

So, what is a Prince Rupert’s Drop?

Well, I will tell you this much, Prince Ruperts’ drops are amazing. What you do to make them, is you get a glob of melted glass on the end of a special glass blowers stick, and then just let it drop into a bucket of water.  This is what it forms: Image result for Prince ruperts drop

So here’s the deal. This drop of glass is so tough, that if you wack it with a hammer, it doesn’t break, unless you bump the really skinny tail. Then it literally explodes into  millions of pieces.  This is really weird, because you just can’t break the bulb part thing, unless you nick the tail. Watch this video to learn more! The channel, Smarter Every Day is super cool!

 

 

 

Parts of a Human Ear

If you were to shrink and go inside a Human Ear (it would be really gross, but still) the first thing that you would see a tube with a wall sort of thing at the end of it. The tube is the ear canal and the wall thing is the ear drum.  If you went past the eardrum, you would find yourself in the middle ear.  You could see the stirrup, anvil, and hammer (you know, the smallest bones in your body).  If you keep going, you’ll start going down the Eustachian tube which actually ends in the mouth.  That was the simple tour of the Human Ear. Hope you enjoyed! 🙂
