Oobleck

• A presentation by Nate Holt
• October 2005

What Is Oobleck?

• Oobleck is a substance we can make by mixing
  cornstarch and water in the right proportions.
• Is oobleck solid or liquid?
• How can you tell?
• Appearance
• Feel
• Lets make some oobleck to find out!

The Oobleck Recipe

• To make oobleck, we need to mix ONE PART water
  and TWO PARTS cornstarch.
• Each pair will receive a teaspoon and a
  one-eighth cup measuring cup.
• 1 tablespoon (Tbsp.) 3 teaspoons (tsp.)
• 1/8 cup (cu.) 2 tablespoons (Tbsp.)

4
Making Oobleck (continued)

• Each pair will receive one-eighth cup cornstarch.
  How much water will each pair need to make as
  much oobleck as possible? Which measuring device
  should you use to measure the water?
• Remember these unit conversions
• 1 tablespoon (Tbsp.) 3 teaspoons (tsp.)
• 1/8 cup (cu.) 2 tablespoons (Tbsp.)

5
Solid or liquid?

• Does oobleck LOOK like a solid or liquid?
• Does oobleck FEEL like a solid or liquid?
• Now that we are through with our oobleck, how do
  you think we should DISPOSE of it?
• Pour it down the drain?
• Throw it away in the trash?

6
Not All Liquidy Things Should Be Poured Down
the Drain!

• For instance OIL and GREASE should never be
  poured down the drain
• When hot grease comes in contact with cold water
  in drainpipes and sewers, the grease solidifies
  and can eventually block the flow of water.
• This causes a BACK-UP!

A sewage back-up YUCK!
7
Motor Oil Is Even Worse!

• In 1995, about 706 million gallons of motor oil
  ended up in the planets oceans.
• More than HALF- 363 million gallons- of this oil
  pollution was caused by people pouring motor oil
  down the drain!

Cleaning up after an oil spill in California.
8
How Can We Properly Dispose of Motor Oil?

• Used motor oil can be RECYCLED
• In Oxford, used motor oil can be recycled at
• Autozone, 1901 University Ave.
• Express Lube, 1814 University Ave.
• Advanced Lubrication Center, 2101 W. Jackson Ave.

9
Recycled Motor Oil Is Then

• Reprocessed and used for/by
• Industrial space heaters
• Asphalt plants
• Paper mills
• Steel mills

10
What Is MERCURY? Hint Were Not Talking About
the Planet!

• Mercury is a silver-colored metal.
• When you hear the word metal, what do you think
  of?
• Below is a picture of some mercury. What do you
  notice about this metal? Does it appear to be a
  solid or a liquid?

11
More About Mercury

• Mercury is actually a LIQUID!
• Mercury is used in the production of
  thermometers, barometers, electrical switches,
  some neon-type signs, and dental fillings.
• Mercury can be found in coal. When coal
  containing mercury is burned, the mercury is
  released into the atmosphere.

12
Coal Power and Mercury Bioaccumulation

• Some Mississippi power plants burn coal to make
  electricity, which releases mercury into the
  atmosphere.
• Mercury then settles on Mississippi waterways and
  ends up in small fish.
• As larger fish eat smaller fish, the mercury
  BIOACCUMULATES, or increases in concentration, in
  the larger fish.

13
What Size Fish Do You Eat?

• Most of us eat only larger fish, which will
  contain higher levels of mercury than smaller
  baitfish.
• Because of the bioaccumulation of mercury, there
  is Limit Consumption Advisory in effect at Enid
  Reservoir for catfish and bass longer than 27
  inches!

14
What Can We Do To Minimize Oil and Mercury
Pollution?

• If anyone in your family changes their car or
  trucks oil, ask them to recycle the used motor
  oil.
• Turn off the lights when you leave the room, and
  turn off other electronic devices when you are
  not using them.
• Remember- just because something looks like a
  liquid does not mean it can be poured down the
  drain!
