A teen student delivered a masterclass on the true history of the Confederate flag

Christopher Justice broke it down into incredible details most of us probably weren't even aware of.

Six years ago, a high school student named Christopher Justice eloquently explained the multiple problems with flying the Confederate flag. A video clip of Justice's truth bomb has made the viral rounds a few times since then, and here it is once again getting the attention it deserves.

Justice doesn't just explain why the flag is seen as a symbol of racism. He also explains the history of when the flag originated and why flying a Confederate flag makes no sense for people who claim to be loyal Americans.

But that clip, as great as it is, is a small part of the whole story. Knowing how the discussion came about and seeing the full debate in context is even more impressive.



In 2015, a student at Shawnee Mission East High School outside of Kansas City came up with the idea to have student journalists document students engaging in open discussions about various topics. In support of this idea, history teacher David Muhammad helped arrange a debate about the use of the Confederate flag in American society in his classroom.

According to the Shawnee Mission Post, Muhammad had prepared a basic outline and some basic guiding questions for the discussion, but mainly let the students debate freely. And the result was one of the most interesting debates about the Confederate flag you'll ever see—one that both reflects the perspectives in American society at large and serves as an example of how to hold a respectful conversation on a controversial topic.

The full discussion is definitely worth a watch. Justice had quite a few Confederacy defenders to contend with, and he skillfully responded to each point with facts and logic. Other students also chimed in, and the discussion is wildly familiar to anyone who has engaged in debate on this topic. For his part, Mr. Muhammad did an excellent job of guiding the students through the debate.

"I had Chris in class, so I knew he was super intelligent and that he read a lot," Muhammad told the Shawnee Mission Post in 2018. "But that really came out of left-field. He was never out there very much socially, so I didn't expect for him to want to speak in front of a crowd like that."

(In case you're wondering, according to LinkedIn, Christopher Justice is now studying political science at Wichita State University after switching his major from sports management. David Muhammad is now Dean of Students at Pembroke Middle School and also serves as a Diversity Consultant.)

Thanks, SM East, for documenting and sharing such a great discussion.

Two Victoria gentleman and a shilling from 1894.

If you had a time machine and woke up in Victorian-era London (1837-1901), you would have difficulty breathing because of the air quality. You'd also walk around plugging your nose because of the poor sanitation and probably be very confused when purchasing anything because of the monetary system.

J. Draper, a London historian and tour guide, explained why money was so different in the Victorian era in a popular YouTube video with nearly 300,000 views. “Let me try and explain how pounds, shillings and pence worked,” J Draper opens her video.


First, in modern-day England, they have two units of money, pounds and new pence, which work like dollars and cents. One hundred pence equals one dollar. However, back in the Victorian era, there was a third unit of money between pence and pounds called the shilling. The shilling was phased out starting in 1971.

To give an example of how money worked in Victorian England, she shared the example of journalist Henry Mayhew, who in 1851 said it costs 21 pounds (£), 9 shilling (s) and 11 pence (d, for denarius) to set yourself up as a baked potato seller. Written out, the cost looks like this: £21 9s 11d.

The breakdown goes like this: 12 pence are in a shilling and 20 shillings make a pound. To further complicate things, there were two more units of money in the 19th century: the 1/4 pence, known as a farthing and a 1/2 pence, known as a half penny (pronounced "haypnee").

"I hope this helps, but like with any measurement system, there's no substitute for just practicing it," J. Draper concludes her video.





Cage for reviving canary, with oxygen cylinder, made by Siebe Gorman & Co. Ltd, London.

These days the phrase "canary in the coal mine" is used to refer to any early warning sign of trouble or danger, but it's based in the real history of canaries being used in coal mining. Miners would carry the songbirds into the mine with them as a makeshift carbon monoxide alarm, as the bird's small body would be impacted by the odorless gas first, giving miners time to evacuate before it built to deadly levels.

Many if not most of us probably assume the canaries used for this purpose gave up their lives to save the coal miners. As it turns out, that was not always the case.

In fact, the man who created the canary in the coal mine system went out of his way to make sure the birds could do their job safely.


After a deadly explosion in a Welsh mine in 1896, Scottish physiologist and leading expert of respiration John Haldane was asked to investigate to find the cause. He concluded that a buildup of carbon monoxide was to blame and suggested using birds or mice—animals that would be impacted by the gas far quicker than humans—to serve as sentinel species inside the mine. Because they are more sensitive to the toxins, they'd get sick (or die) before the gas reached levels that would harm or kill humans.

Canaries were determined to be ideal for this purpose because they use an immense amount of oxygen in addition to being small and portable. Their breathing habits allow toxins in the air to circulate through their bodies more quickly, giving a very early warning for carbon monoxide gas.

But rather than carry the canary into the mine in a normal birdcage as a potential sacrifice for the greater good, Haldane created a specialized cage that would allow them to live.

The "canary resuscitator" cage held the bird in a clear enclosure with a circular door that was kept open to allow air to enter through a grill that the bird from escaping. As soon as the bird showed signs of gas poisoning—swaying on its perch or collapsing—the door would be closed and a valve connected to a small oxygen tank on top of the cage would be opened. The bird would then get fresh air and the effects of the toxic gas would be reversed.

The "canary resuscitator" protected the canaries from getting too much poisonous gas.

The Board of Trustees of the Science Museum

Lewis Pollard, who served as an assistant curator at the Science and Industry Museum in Manchester, U.K., shared that the canary resuscitator was his favorite out of the museums more than 20,000 objects in 2018. "While I don’t advocate the use of animals in testing dangerous conditions, I am pleased that Haldane spared a thought for the canaries themselves and worked to make their job as non-lethal as possible," he wrote. "My impression from hearing about canaries in coal mines was that they were expected to die to warn people, so when I came across this object it was a huge relief."

There were "less thoughtful" cages used as well, Pollard added, but Haldane wasn't the only person wanting to prevent the birds' demise.

"I’ve even read that many miners cared deeply for their canary companions, and some disliked the advent of electronic sensors in the mid-1980s because it meant they would lose this companionship," wrote Pollard.

Clearly, it's better not to use animals to check for poisons when there are other options, but when the canary in the coal mine was the most viable way to prevent tragic mining accidents, it's nice to know it was done as ethically as possible.
