Cody's Lab: Floating an Anvil in Mercury

In this video, Cody revisits an experiment to float an anvil in mercury. After a previous attempt failed, he uses a larger tub of mercury to successfully demonstrate the floating of a 110-pound iron anvil. The video explains that mercury's density is nearly twice that of iron, allowing the anvil to float better than wood in water. Cody also tests the sound and stability of the anvil while floating, noting that the mercury deadens the sound, making it less harsh on the ears. The video concludes with Cody's observations and a humorous note about getting mercury in his glove.

What was the main reason Cody decided to try floating the anvil in mercury again?

• He wanted to test a new theory.

• The previous attempt was unsuccessful.

• He received a new anvil.

• He wanted to make a viral video.

What was the initial weather condition described by Cody at the start of the video?

• Rainy and cold

• Cloudy and humid

• Windy and hot

• Breezy and perfect

What did Cody use to clean the surface of the mercury?

• A dry cloth

• A wet rag

• A sponge

• A brush

What was the weight of the iron anvil used in the experiment?

• 110 pounds

• 75 pounds

• 150 pounds

• 50 pounds

Why does the iron anvil float in mercury?

• Because iron is less dense than mercury

• Because iron is magnetic

• Because mercury is a solid

• Because the anvil is hollow

What happens when Cody pushes the anvil down into the mercury?

• It bobs up like a cork

• It dissolves in mercury

• It stays submerged

• It sinks to the bottom

What effect does the mercury have on the sound of the anvil?

• It has no effect on the sound

• It dulls the sound

• It makes the sound echo

• It amplifies the sound

Why might it be beneficial to have an anvil sitting in mercury while working?

• It increases the anvil's weight

• It reduces the noise

• It prevents rust

• It makes the anvil easier to move

What unexpected item also floated in the mercury?

• A screwdriver

• A wrench

• A nail

• A hammer

What humorous observation does Cody make at the end of the video?

• He lost the anvil in the mercury

• He forgot to record the experiment

• He dropped the camera in mercury

• He got mercury in his glove
