Gack- The Making's

Materials:
Boron
Stick
Spoon
Water
Baking Soda


Procedure:
Put some glue in a cup. Add water to it, about the same amount of glue. Stir. When slightly combined and a bit of baking soda. Apprimetly a teaspoon. When totally combined add 3 drops of Boron.

Outcome:
If you followed the procedure above you will get a sticky goo. That can stick to walls. faces etc.

My Experience:
After following all the steps above came out with a really nice slightly stringy Goo, Gack.

What it will feel like if done wrong:
If you come out with a not so gooy gack that feel like with gelled powder. You added to much baking soda. This is the only thing that could really mess up your experiment. But then there are minor things like to much water or too little water. Or too little boron. But all three are fixable.

Heat Resistant Make-up

As many of us know people are out their risking their lives for us. Enduring guns, bombs etc.

To better hide and protect them selves soldiers use camouflage. They use camouflage clothes, helmets, and face paint. Recently the army along with chemists have created a special face paint. A more make-up rather than face paint. They created a heat resistant camouflage make up. Like I said there are bombs. Each bomb blast send pressure waves but along with those waves it also send sizzling 600 degree celcius heat wave. Enough to burn up the first layer of any soldier. Enless they are wearing heat resistant camouflage Make-up. 

Some major characteristics that this make-up had to qualify: "It had to be easy to apply and remove; waterproof; not irritate the eyes, nose or mouth; and resist rubbing off easily. And like today’s makeup, it had to come in light brown (“sand”), dark brown (“soil”), green (“jungle”), white (“snow”) and black colors. Finally, it had to include as much as 35 percent DEET. That’s an insect repellent, but one that happens to be highly flammable."

Like one can only imagine this life saving make up is extremely hard to make and took lots of time in the lab.
The chemist behind this invention is Robert Lochead. He and his team made this incredible make up by replacing all the burning ingredients such as fatty oils or hydrocarbs and replaced them with silicones. The team of chemists then used their chemical techniques to make all the particles of the "pigment" to clump. This would endure more heat. As for the color, they just used the individual pigment mixed with whatever chemical. And lastly they mixed in the 35 % gel like DEET.

Chemists save lives! Did you know that?
