The Ultimate Wave Pool Quiz
by Staff
Modern civilization loves to re-create nature. We have artificial light, artificial Christmas trees, artificial grass, artificial hearts and even artificial beaches! Curious as to how an artificial beach actually works? Take our quiz and get a behind-the-scenes glimpse at the workings of the giant wave pool "Thunder Bay" in Greensboro, North Carolina.

In the ocean, how are waves created?

  • through the magnetic pull below the earth's surface
  • through wind
  • through water pressure

What do you need to recreate a simple wave in a pool of water?

  • You need some means of creating a periodic disturbance.
  • You need a water pump or a hydraulic piston.
  • You need at least five gallons ( 19 liters) of water.

What is the name of the kid's wave pool at Emerald Pointe's water park?

  • Kiddies' Bay
  • The Ultimate Kid's Wave Pool
  • Splash Island

What does Splash Island use to generate a disturbance in the water?

  • a high speed fan
  • an oscillating plunger
  • a rotating paddle

What kind of valve is used inside the wide metal pipe at Splash Island?

  • a diaphragm valve
  • an hydraulic valve
  • a butterfly valve

What makes the butterfly valve rotate?

  • an hydraulic piston
  • a pump
  • an electric timer

Why can't Splash Island's wave generating system be used to create enormous, surfable waves?

  • Its system works only for pools of water that contain less than 1, 000 gallons (3, 785 liters ); you need more water than that in a large wave pool.
  • It can, it is just not cost effective.
  • It would require too large a force.

How many basic parts are there to a large wave pool?

  • three
  • five
  • 10

What can the functioning of the giant wave pool, Thunder Bay, be compared to?

  • a toilet
  • a bath
  • the ocean

How is Thunder Bay kept sanitary?

  • It uses extra strength chlorine.
  • The water is changed daily.
  • The water is continually filtered.

How much water does Thunder Bay hold?

  • 500,000 gallons (1.9 million liters)
  • 1,000,000 gallons (3.8 million liters)
  • 2,000,000 gallons (7.6 million liters)

What are the measurements of Thunder Bay's pool?

  • 36 feet (11 meters) wide, 250 feet (76 meters) long
  • 50 feet (15 meters) wide, 200 feet (61 meters) long
  • 84 feet (26 meters) across, 400 feet (122 meters) long

How many water pumps does Thunder Bay have?

  • one
  • two
  • three

What is a valve seat?

  • the reservoir opening
  • the main part of the valve which prevents the water from releasing from the reservoir
  • the mechanism which pumps water into the reservoir

What plugs and unplugs the valve seat?

  • an hydraulic pump
  • a valve plate
  • the pump unit

What makes the valve plate move?

  • an hydraulic-cylinder piston
  • a motorized pump
  • the pressure from the water

Why is Thunder Bay's hydraulic piston fuelled by vegetable oil instead of regular machine oil?

  • Machine oil is water soluble, while vegetable oil is not.
  • There is a risk that some oil may leak into the pool water.
  • It is more cost effective when using such a large amount.

In a hydraulic piston, if the pressure is higher on the left side, in which direction will the piston move?

  • right
  • left
  • forward

What is a solenoid?

  • a type of motor
  • an electromagnetic switch controlled by an electric current
  • pressurized gas

What is so amazing about this wave generating system?

  • It is extremely durable.
  • It uses a very small amount of electricity.
  • It moves tremendous amounts of water.
