How to Make a Solar Eclipse Viewer

Most of you are from North America, and I’m sure you know about the solar eclipse next Monday, right? The path of totality will cross the United States, but all of North America will get to see it to varying degrees of partiality. For me, it’ll be around 75% partial.

Do you have your solar eclipse glasses? They’re hard to find now. If you don’t have some, don’t worry! You can still observe the eclipse! Actually, I made one today with my daughter. Here it is:

An easy to make solar eclipse viewer made with a cereal box.

That’s right, it’s a cereal box. Curious how to make it? It’s actually very easy. I made a video showing how I made it, so if you want to try this out, then definitely watch the video!

Are you going to make it? Any kind of cereal box will do. You can use pretty much any kind of box, actually. Just make sure no light is getting in except through the pinhole. Let me know if you’re going to make it!

Why Aren’t There Many Male Booktubers? The Jay Dee Show 33

I did some more frequent video publishing in the past week, but not quite what I used to do. The science videos have returned, as well! I posted 4 videos this week on 2 channels.

On my main channel, I posted a little less than I expected, but I did get 3 videos up! Let’s check them out.

First up is a Japan travel vlog, but it’s more about culture than anything a tourist would see. In fact, unless you’re invited to a funeral, you won’t get to see this! I talk about the 49th day of the traditional Buddhist funeral in Japan.

Next up is a new phenomenon on Booktube. Jayesh Chhaya opened up the topic about male booktubers. Where are they? Why aren’t there as many males booktubing as females? He created the Male Booktuber Tag, and I did it.

I continued my regular Authors Answer series on video with #32, all about writing controversial topics.

On my science channel, I uploaded 1 video, a video I’d recorded way back in April. Yeah, so it’s a bit old. I’m still dressed for cold weather. It’s the continuation of the A to Z Challenge, this time the letter E. It’s all about Jupiter’s moon Europa!

I can’t say how much I’ll be uploading over the next week, as I don’t know what’s going on with my job. It really depends on that. But I will be doing the Q&A for my 1 year anniversary on booktube, and hopefully a new Star Trek video. Definitely more Japan videos, though! And coming in the next day or two (maybe even today) is the next science video. Keep checking back and subscribe to my channels!

Which video did you enjoy? Let me know in the comments section.

Star Trek: Discovery Trailer! The Jay Dee Show 30

Another week gone, and some videos to watch! Not as many as I’d hoped, though. But I think we’ve got some good stuff here. Actually, there were only two videos, one on each channel. But they are both worth watching.

On my main channel, I uploaded one video. And it had to do with Star Trek: Discovery! You see, the first trailer was released, and I had some interesting impressions about it. So, check out my Star Trek: Discovery trailer reaction!

On my science channel, I finally resumed uploading videos. I explained what happened in the past month, but also have a big request. And I want to ask you, too. Is there a science topic or question you’d like me to answer? If so, let me know in the comments section below or on the video. Check it out!

More to come next week. Definitely some Star Trek, a top 5 list about science fiction, Authors Answer, and some science! And a very, very special video that will be up tomorrow. It deserves its own blog post.

Let me know what you thought of these videos in the comments section below. And what did you think about the Star Trek: Discovery trailer, if you saw it?

You Can’t Please Everyone – Comments

Over the last couple months, I’ve been receiving a lot of comments on two posts which talk about things that bring a lot of controversy. One is about politics, the other is about climate change.

I’m better at talking about climate change, so I don’t have a problem rebutting climate change deniers’ claims. One comment questioned what I said in the post and provided some information about Mt. Etna’s CO2 output, thinking he won the “debate.” Well, the information he told me matches what was said on Snopes, as well as scientific sources. It only confirmed what I’d said. That backfired.

And about Snopes, if I refer to a Snopes article, don’t say it’s not a legitimate source. You know why? The information they give references scientific journals, government research, and other legitimate sources.

But then, we get to the political post. The topic doesn’t matter, but what does matter is how people comment. I was insulted in a rather crude manner. The first rule on this blog for comments is this: Do not insult anyone. The second rule: Be civil. These people broke those rules.

If you want to have a constructive conversation, then behave. Use intelligent arguments, not reactionary ones. Don’t use all caps on random words. Whenever I see comments like that, I can pretty safely assume that the person is irrational and illogical. All caps don’t make an argument stronger, it makes the person look like they’re shouting. Don’t call me or other commenters idiots. Behaviour like this makes a person less credible. It’s not worth my time to debate with people like this.

Now that I got this off my chest, I’ll return this blog to normal.

Everything Derailed! The Jay Dee Show 27

Things were going so well. The A to Z Challenge had begun, I was getting videos out on time, and then it happened. Derailment. I caught a cold so strong that I had very little energy. And just as I’d recovered, I started working 10 straight days on something that was physically demanding. Again, energy sapped. But I should be getting things back on track now!

First of all, my main channel has had no new videos. I have a couple coming up, though. Already recorded!

Moving on to my science channel, there are 3 videos to report to you!

First is the letter B. It’s 10 Facts about Bees!

Moving on the letter C, it’s 10 Facts about the Canada Goose.

And then for the letter D, it’s 10 Fact about DNA.

They’re all about biology, surprisingly. I already have the E video ready to edit and upload, which I’ll do tomorrow.

What do we have in store for the next week? Videos! I plan on continuing the A to Z Challenge, even though it’s finishing. I’m not quitting. For my main channel, it looks like I may have a tag video to do, as well as some vlogs. I’ll be working on the regular weekly videos, and maybe more! I should get back to doing Japan videos, too.

So, which video did you enjoy the most?

D Is for DNA

This post is coming a day late. I hope that’s not a problem with the rules of the A to Z Challenge! You see, I have some foreign DNA in my body. The common cold. I was too tired to get the video and post up last night. But here it is now! For the letter D, I’m talking about DNA. How many of these facts did you know?

And here are the facts:

  1. DNA stands for deoxyribonucleic acid.
  2. A DNA molecule is made up of two bipolymer strands wrapped around each other to form a double helix.
  3. There are four nucleobases represented by the letters C, G, A, and T. They are cytosine, guanine, adenine, and thymine.
  4. Nucleobases pair up, A with T and C with G to connect the two DNA strands to form the double helix.
  5. Only 2% of human DNA codes protein sequences. The remaining 98% have other various functions, which would require another full video to talk about.
  6. The species with the largest number of chromosomes is the ciliated protozoa with 29,640,000.
  7. The species with the fewest number of chromosomes is the jack jumper ant with only 2. But that’s for the females. Males are haploid and have only 1, the smallest number possible.
  8. Humans have 46 chromosomes, but other great apes, including chimpanzees, gorillas, and orangutans, have 48.
  9. More than 8% of the human genome is made up of retrovirus sequences.
  10. There is a 4% difference in the genomes of humans and our closest relatives, chimpanzees and bonobos.

E Is for Europa

Even though the A to Z Challenge is over, and I took a huge break, I’m going to finish it. A lot has happened over the last couple months, but it’s back! Today is the letter E, and I’m talking about Jupiter’s moon Europa! Did you learn anything new?

  1. Europa is the fourth largest natural satellite of Jupiter.
  2. It was discovered in 1610 by Galileo Galilei, along with the other three Galilean satellites.
  3. The surface of Europa is the smoothest surface of any world in the Solar System, consisting of water ice.
  4. Europa orbits Jupiter in just 3.55 days, with one side always facing Jupiter, as it’s tidally locked.
  5. Beneath the ice crust is an estimated 100 km deep ocean of salt water. But it isn’t clear if the ice is thick or thin. However, the amount of water on Europa is about two to three times the volume of Earth’s oceans.
  6. Europa has a weak magnetic field, best explained by Europa’s salt water ocean.
  7. Tidal heating from the interactions of Europa with Jupiter and the other Galilean satellites warms the interior of the moon, possibly resulting in hydrothermal vents at the floor of the ocean. This has led scientists to suggest that life may exist in Europa’s ocean.
  8. Europa most likely has an iron core and a rocky mantle.
  9. Observations by the Hubble Space Telescope provide further evidence of subsurface oceans, as plumes of water have been seen erupting to 200 km above the surface.
  10. Europa has an oxygen atmosphere. But it’s very thin, providing a surface pressure of only 0.1 micropascals.
