BCP 201 FD: v3 (Second Timers)

MIGHTY FEATHERS 1: The entire feather, the rachis-–or shaft– and the barbs growing from the rachis shaft and the tinier barbules with their hooks and hook catchers or mirrors–are all made of the same protein keratin. However, feathers are a complex composite permeated also with nano-strands of collagen.

MIGHTY FEATHERS 1: Keratin also makes up lion claws, horse hooves, rhino horns–and your toe nails too!

MIGHTY FEATHERS 1: As the feather is forming, blood flows up the rachis tube. At this stage, it’s called a blood feather because of the blood-filled tube. As the feather grows, the blood supplies all of its needs for its incredible construction job. The feather eventually empties of blood leaving a clear rachis.

MIGHTY FEATHERS 1: Egrets, penguins and herons produce continuously growing powder down feathers. The down feather’s tips break off and create a cleaning powder like talcum powder. The birds rub this into their feathers and it cleans them.

MIGHTY FEATHERS 1:   The peacocks’ astonishing eye feather has no color. It’s instead equipped with flat, exact-width keratin-layered mirror barbs.  These destroy and amplify light. These light-destroying feathers make the colors of the peacock feather.

MIGHTY FEATHERS 2: Peacock eye feathers have 1 million DNA-designed barb mirrors with precise layers.  These create one of the prettiest feathers on the planet– using only mirrors

MIGHTY FEATHERS 2: Critical primary flight feathers located on the end of bird wings are all built with the correct strength that each bird needs. There are the super-strong feathers of the 80 beats-per-second wings of some hummingbirds and the wildly strong primary feathers of the 200+ mph peregrine falcons –and feather strengths for everything in-between!

MIGHTY FEATHERS 2: Some manakin bird species make machine-gun-like sounds called sound-nations with their wings. When they are whipped by the small birds, the feather ends move at over 767 mph to make miniature sonic booms! This is faster than the speed of sound!

MIGHTY FEATHERS 2: Some feathers are crazy long like the six-foot super-long Reeves Pheasant tail feathers.   Other feathers like those on the face of seagulls are so tiny that they look like hairs with every one grown at exactly the right length and direction. Amazing!

THE CARB’S VENTURI: You get liquid gas at a gas station . It is exploded inside the cylinders of your car engine by a spark from the spark plug. The power pushes the piston in the cylinder chamber with tremendous power.

THE CARB’S VENTURI:   The oil in the engine of the car must be turned into a vapor before it is injected into the cylinders.

THE CARB’S VENTURI:   The venturi inside the carburetor speeds up the flow of the air rushing into the carburetor.

THE CARB’S VENTURI:   There’s an experiment that we do in science classes where we use a 5 gallon water bottle.  It makes a loud whoosh sound.

THE CARB’S VENTURI:   Carburetors use the venturi effect to mix gas with air.

THE CARB’S VENTURI: Above the venturi of the carburetor is the butterfly valve (choke valve). When you press the gas for more uumph in your car, the valve becomes vertical–up and down. This allows for maximum air flow. This pulls in more gas and the increased amount of air-gas mixture is sent to the cylinders.
