Flubber and Penny Experiment Concepts

The video tutorial explores the properties of liquid nitrogen, demonstrating its ability to freeze objects and create fog. It provides safety tips for handling extremely cold items and offers a hands-on activity to make flubber using household materials. Additionally, the tutorial includes a chemistry demonstration on turning copper pennies into gold-colored ones by heating them with zinc. The session concludes with an invitation to participate in the activities and learn more.

What does the fog created by liquid nitrogen consist of?

• Condensed water vapor

• Liquid nitrogen itself

• Dust particles in the air

• Smoke from a fire

Why is it important to use special gloves when handling cold objects?

• To make the objects warmer

• To keep the objects clean

• To avoid frostbite on your fingers

• To prevent the objects from melting

What is the first step in making flubber at home?

• Mixing Borax with water

• Heating the mixture on a stove

• Combining Elmer's Glue with water

• Adding food coloring to water

What household item is used as a laundry booster in the flubber experiment?

• Baking soda

• 20 Mule Team Borax

• Vinegar

• Salt

What happens when you mix the glue solution with the Borax solution?

• It evaporates

• It becomes sticky and snotty

• It turns into a liquid

• It becomes a solid block

What is the first step in creating a gold penny?

• Painting the penny

• Washing the penny

• Turning the penny silver

• Heating the penny

What two metals are combined to create a gold penny?

• Copper and silver

• Copper and zinc

• Gold and copper

• Zinc and silver

What is the purpose of the shield in the penny experiment?

• To enhance the reaction

• To keep the solution warm

• To prevent touching the solution

• To protect the pennies

What is the final step in the presentation?

• Making more flubber

• Cleaning up the materials
