Flushing Mercury Down a Toilet: What Happens?

TLDRIn this video, Cody's Lab conducts an interesting experiment to see what happens when flushing mercury down a toilet. He starts with a small amount of mercury and gradually increases the quantity. Eventually, he manages to clog the toilet with the heavy metal. Cody also tests the behavior of gold and lead in the toilet. The experiment concludes with an attempt to recover the mercury and clean up. Watch the video to see the surprising results!

Key insights

🚽Flushing mercury down a toilet can actually lead to clogging, as demonstrated in the experiment.

💧Mercury, being a dense liquid, can be flushed through a toilet in small amounts.

⚖️Gold sinks in mercury due to its high density, while lead floats on the surface.

🧪Nitric acid can be used to dissolve the mercury coating on gold.

🧹Cleaning up after the experiment involves disassembling the toilet and recovering the mercury.

Q&A

Can mercury clog a toilet?

Yes, flushing a large amount of mercury down a toilet can lead to clogging, as shown in the experiment.

What happens to gold and lead in the toilet?

Gold sinks in mercury due to its high density, while lead floats on the surface.

How can the mercury coating on gold be removed?

The mercury coating on gold can be dissolved using nitric acid.

Is it safe to conduct this experiment?

This experiment should only be conducted by professionals in a controlled environment due to the toxic nature of mercury.

How should the mercury be cleaned up?

Cleaning up after the experiment involves disassembling the toilet and safely recovering the mercury.
