He loves me...he loves me not...

Ethylene is the gas that causes blossoms to fall. In nature, it's a plant hormone. It is also used in a controlled way because fruit is picked before it is ripened and then travels to the destination spot as so. When it finally arrives, a whiff of the gas is given to ripen the fruit to be of a consumer's use.

What could be stronger than steel, might you ask?

Maybe you all remember the video we watched in chemistry not too long ago about Kevlar. If so, here's a refresher... Kevlar is a plastic that can stop bullets. It's used in some things such as bullet-proof vests, helmets, and planes. The material is resistant to fire. What makes it so strong is that the fibers in it are in organized, parallel lines- not just a mess. When it's spun into fibers and then heated, it becomes even stronger and is used for military armor, space suits, and safety gloves. It's also 5x stronger than steel and more elastic than carbon fiber. Kevlar is hard to compress and to paint so instead of being used on a car, it's used in the driver's cell when it comes to racing cars. It isn't affected by long exposure to weathering or to the sea.

Indestructible Glass and the Man That Went With It

In 37AD an unknown man created unbreakable glass. He foolishly showed it to Tiberius, who was the Emperor of Rome at that time. Tiberius killed him and ruined his workplace because he didn't want anyone to have the knowledge of that special material. The man used a form of sodium borate which is the key ingredient in Pyrex glass. Pyrex glass is the presently known unbreakable gass. If it wasn't for Tiberius who destroyed the man's work we would have had that glass since then...

To Be Bitter, or Not To Be Bitter? That is the question

Bitrex Taste Test


Bitrex: the chemical name for it is denatonium benzoate. It's a non-toxic white powder. In order to obtain the piercing bitter taste, you only need it in small quantities. To give you an idea of how bitter it really is, Bitrex is in the Guinness Book of Records as the bitterest substance known. It is added to household chemicals so that if it is consumed by a child then they will spit it out immediately.

Rhino Horns

Keratin is present in rhino horns. This is THOUGHT to be the best aphrodisiac of all. It is also in fingernails. There are no beneficial effects of eating keratin and it does not arouse anyone. Unfortunately, rhinos are still being killed because the thought of their horns having a sexual stimulating quality. To me, it seems ridiculous because keratin does not give you any of those feelings! Greedy, misinformed people!):


How can we stand to turn something so innocent into this?
