EDIBLE Fake Barf

Ingredients: 1 packet unflavored gelatin, apple sauce, powdered cocoa, oatmeal, raisin bran cereal.

Instructions:
Place 1/4 cup of apple sauce into the frying pan.
As you heat the apple sauce, add 1 packet of unflavored gelatin, stir.
To the mixture add 1-2 pinches of powered cocoa and stir thoroughly.
Turn off the heat.
Pour a small amount of oatmeal into your palm and sprinkle into the mixture.
Don't stir all of the way so that you get some areas of chunky bits.
Now do the same for a palm-full of raisin bran.
Remove the barf from the pan and place onto a plate.
Spread out the barf and shape it until it looks real.
You may want to stick in some raisins or cereal bits.
Allow the barf to cool on the plate for several hours.
Once cool, use the spatula to remove the barf from the plate.

Make Some Snot (NOT edible)

What you need
A small plate (the lid of a yogurt container works well)
Popsicle stick
Film canister or zipper sandwich bag
White glue (not school glue)
Water
Dropper or spoon for water
Green Food coloring
Dropper or spoon for Borax solution

To make the Borax solution use 1/4 cup Borax to 1 litre (1 quart) of hot tap water. Stir well. There should be some Borax left in the bottom of the container. If all the Borax dissolves, add more until no more will dissolve. Let the solution cool.


What to do
Put about a tablespoon of glue on the plate.
Add a few drops of water and stir with the popsicle stick.
Add a couple of drops of food coloring and stir.
Add a teaspoon of Borax liquid and stir.
The fake snot should start to gloop up on the stick.
Pick the fake snot up and roll it in your hands until it has a nice texture.
Fake a sneeze into your hand. Let the fake snot goop out between your fingers. GROSS!
Store your fake snot in the film canister.
Snot is amazing stuff. You need it to help keep dust, pollution and other junk out of your lungs. Tiny hairs in your sinuses, called cilia, move the snot toward your throat, where you swallow it.

Good snot is clear and colorless. But when the cilia stop moving, your nose mucus gets clogged. Bacteria, bacteria waste, and other stuff gets stuck. The mucus changes from a clear liquid to gunky green.

Where do boogers fit into the snot picture? The mucus coats the hairs inside your nose. The scientific name for nose hairs is vibrissae. When you breathe in, dirt gets trapped in the goopy hairs. The dirty mucus clumps up, dries out with your breathing, and a booger is formed!

Blood and Gore (NOT edible)

What you need
Materials for fake blood:
Toothpick
Cup
Spoon
Zipper sandwich baggie
2 spoonfuls of "white" corn syrup
Spoonful of water
Red food coloring
Cornstarch
Cocoa

Materials for fake wound:
Petroleum jelly
Red food coloring
Plate
Tissue
Cocoa powder


What to do
Place two spoonfuls of clear syrup into a cup.
Add one spoonful of water.
Stir with a toothpick.
Add two drops of red food coloring.
Stir with the toothpick.
Pour the mixture into a baggie.
Add two pinches of cornstarch and one pinch of cocoa to the mixture.
The red food coloring will stain your clothes, so don't use your fake blood when you're wearing your favorite outfit!

This blood is nontoxic, which means you can put it in your mouth and then let it drip out and say "I want to suck your blood".
Have you ever eaten blood? Blood is very nutritious stuff. It contains lots of protein and protein is necessary for a balanced diet.

Have you ever tried a blood milk shake? The Masai people in Africa give blood milk shakes to people who are elderly or ill. The Masai are a herding people. They make a blood milk shake by cutting a vein in the neck of a cow and collecting some blood. Then they mix in some milk. A blood milk shake is actually very nutritious. Maybe you haven't tried a blood milk shake, but have you ever eaten a rare steak? So you have probably eaten blood after all.

What color do you think of when you think of blood? Most people think of red. You might be surprised to learn that it is deep blue or purple. When you cut yourself, the blood is exposed to air and it oxidizes. That's a fancy way of saying that it rusts. Blood has iron in it, and iron turns red when it rusts. Have you ever cut yourself? If you cut yourself really badly, get an adult - you might need to see a doctor. But if you cut yourself just a little, how long do you guess it takes before you stop bleeding? On average it takes about 6 minutes before you stop bleeding. The next time you get a small scrape you might want to time it.

When you cut yourself, your brain says, ACK! Save me! Your body goes into immediate action. It sends out special cells called platelet cells to the wound site. The cells change and become sticky. They form a net that stops blood from dripping out. Then the macrophages arrive. These are very large white blood cells that look like pom poms. The macrophages actually surround and engulf bacteria, dirt and other foreign invaders. Finally, your body sends out killer cells that come and mop up the dead macrophage and bacteria. The whole time, a dried blood bandage (or scab) is forming.

To make the blood, you goop some petroleum jelly onto a plate. Add some red food coloring and mix. Add cocoa powder and mix. Place some tissue on the wound site. Smear the petroleum jelly over the tissue. Mold the tissue until it looks like ripped skin. Rub in some cocoa powder around the edges so it looks like it's scabbing over.

Every Breathe You Take

What you need
A calculator


What to do

You breathe twelve times each minute. To find out how many times you breathe in one hour, multiply 12 by 60.

For the number of breaths in one day, multiply your answer by 24.

Now take this answer and multiply it by 365 to find out how many times you breathe in one year.

To calculate the number of breaths you have taken in your life, multiply the breaths in one year by your age.

For figuring out how much air this is, choose an amount and multiply by 0.5 or one-half. By using the proper answers from your calculations, you can tell how many liters of air you expel each minute, hour, day, year, or lifetime.

The next time you are in the soda section of the grocery store, count how many liters you breathe in one hour.

Ear Wax

What you need
A small flashlight or a penlight that works
A plastic bottle
Scissors
Paint and a brush or permanent marker
Tape
A willing volunteer

What to do
Remove the cap of the plastic bottle. Use the scissors to cut off the top part of the bottle, so that you end up with something that looks like a funnel. Trim the top of the bottle until it fits snugly onto the end of the flashlight. Cost the inside of the bottle top with dark paint or permanent marker. Allow the paint or marker to dry. Tape the top of the bottle to the end of the flashlight. Find a willing volunteer. To look into the right ear, have your volunteer straighten the ear canal by pinching the back of the ear flap, then pullit it upward and toward the back of the head. Place your ear wax detector up to the opening of the ear canal. Turn on the flashlight. Conduct your ear wax search. Say things like "How many years have you had a dime stuck in your ear?"
The ear has three parts: the outer, middle, and inner ear. The outer ear is the part you can observe by using your eyes. The outer ear is also where ear wax, or cerumen (suh ROO men), is made. Inside the ear canal are about two thousand special sweat glands. These glands don't make sweat; they make wax. Ear wax coats the inside of the ear canal to trap any nasty stuff like dirt, dust, and bugs that get into your ear. People who live in areas with a lot of junk in the air, such as New York City, make more ear wax. Once something is stuck in your ear wax, the wax becomes less sticky, clumps, and falls out. To search for waxy build-up, take a look into the ear of someone you love.

Burps and Belches (NOT edible)

What you need
Vinegar
Baking Soda
Medium or Large Balloon
Funnel

What to do
If you do this over a sink, there is much less clean-up at the end!

The balloon is your stomach. Pour a small amount of vinegar into the bottom of the balloon, your stomach.

Use the funnel to add baking soda to the balloon stomach. Pinch the balloon closed with your fingers at the neck; this is your esophagus.

Watch your balloon stomach expand with gas. Unpinch the esophagus to release the gas, or burp.

Practice the pinch release to see whether you can make the belch sound like a real burp.
Burp, belch, and eruct (eh RUCT) are all names for the same thing. Everyone does it! In fact, you burp about fifteen times every day. People who eat fast, talk while they chew, or suck on cigarettes or cigars burp more often. But that's nothing ... a single cow can fill up two refrigerators with burp gas each day.

Your stomach is like a balloon. The stomach stretches as food, liquid, and air are added. When you eat and drink, you swallow air; which adds gas to your stomach. When the stomach digests, it adds acid to the foods and creates gas of its own. So even more gas enters your stomach. If your stomach builds up too much gas, the pressure becomes too great. Gas must escape to release built-up pressure. Burp!

Sweat (NOT edible)

What you need
Cotton ball
Rubbing Alcohol
Your Forearm
Your breath

What to do
Get the cotton ball wet with rubbing alcohol. Swipe your forearm to get it wet with the alcohol. Blow on the wet part of your forearm. What do you feel?

When the water in sweat evaporates, or turns into a gas, it takes away heat.

Rubbing alcohol evaporates even faster than water, so you can feel the effects right away. Except for your lips and a couple of the reproductive parts, your body is covered with little sweat producers, or sweat glands. On your palm are more than 2,000 sweat glands in an area about the size of a postage stamp. Sweat glands ooze lots of sweat out of the little openings, or pores, in your skin. Up to a quart of liquid in an average day.

Smelly sweat comes from sweat glands located mostly in the armpits but also in the crotch, anus, and a little on the scalp. Until a person gets to be about twelve years old, these glands don't do anything. After age twelve, they start oozing, and they never stop. That's why adults are so stinky, and kids aren't.

Dogs don't have many sweat glands, so they sweat by panting. A cat's sweat glands are in the soft pads on the bottom of the feet.

Sweating is really important. It controls your body temperature. When you exercise or when the outside temperature gets warmer than 87-degrees or when you get really nervous, your body's air conditioning goes on. The sweat coats the surface of the skin to remove heat from the body. Evaporation of the water cools you down. Salts and urea (yur EE a) are left behind. That's why you taste salty after sweating. It is also why you feel sticky.

Saliva Magic: Turning Starch into Sugar

What you need
Yourself
A soda cracker (salt free works best)
A little time

What to do
Put a mouth-size piece of soda cracker on your tongue. Close your mouth but don't chew. Leave the cracker there for several minutes to let the saliva do its thing. Remember, DON'T CHEW! After several minutes, swish the cracker in your mouth and swallow. How did the cracker taste?

Salts, gases, antacids, mucus, chemicals that break down food are called enzymes (EN zimes), and urine. A small trickle of urine enters your mouth from the places in your body that make saliva. These are called glands.

Your spit factories are located in several glands. Many tiny glands line the inside of your cheecks and ooze small amounts of saliva. Pairs of spit makers are hidden in front of each ear, under the tongue, and beneath the lower jaw. Spit travels in tubes, or ducts, from the glands to pour spit into the mounth. Think of a liter soda bottle. That's about how much saliva enters your mouth every day. Now think of 190 liter soda bottles. That's how much saliva a hay-eating cow produces daily!

Spit is great stuff. It gets food wet so it's easy to swallow. It kills bacteria in the mouth that can cause cavities. It's a natural mouthwash. And it turns starch into sugar. The enzymes in saliva break apart long starch molecules and turn them into short sugar molecules. Life is sweet with saliva around.
