Can Crushin' Experiment
Just a little experiment where we explore the properties of water and the effects of expansion and contraction of water from liquid into gas, and from gas back into liquid. We can observe how this can create a vacuum which can cause a can to be crushed. Very fun experiment!

I Saw a Hawk (and why that matters)
Просмотров 62 часа назад
When I was a kid I never ever saw a hawk once. Now it is a pretty common occurrence for me to see Hawks swirling over the Don Valley Parkway and just generally around the city of Toronto where I live. This is a very exciting development, it has to do with the fact that we stopped using DDT because it was killing the big birds. Guess what, and we made a change. The big birds came back. It is pos...
Another Day on the Water, Pog Lake
Просмотров 1714 часов назад
Another great day kayaking on Pog Lake in Algonquin Provincial Park. We see some birds feathers and discuss whether they are from a fledgling bird's first flight, some beautiful water and sunshine, discuss the origins of the word Ontario in the indigenous language it came from. We also have a beautiful camping and kayaking and traveling on the lake!
Driving through Algonquin Provincial Park

Filming out the window as we drive through beautiful Algonquin Park, taking in the fall colors and the lakes and the general Vibe of Northern Ontario as the colors change. Such a beautiful day! This was filmed as we were heading into our camp site at Pog Lake campground.

Maples are usually pretty nice and red
I'm worried that I get too distracted by hawks when I am driving on the highway. So cool (the hawks are cool, the distraction not so much
Gotdam??? 🦫 beavers do!
You don't need to tell me, I'm a beaver believer.
How serene
@@Saifera it was a beautiful day
This is just my hypothesis, would like to hear what other people think.
Where can i get some dam bait
@@ChadHarsvickjust up the road. You will need a fishing licence though
Double reflection!
Algonquin Park, beaver pond trail?
@@mikebarkerstudio that is correct
I'm pretty dammed up right now. What do you recommend?
@@FritzMoney I'm sorry but I am not a doctor
Careful! I know a lot of guys who lost money chasing 🦫
@@newfdog9602 true. But it is also true that in the early days of Canada the entire economy was based on chasing 🦫
No one cares, damn Canadians. Go back to your shanty
They work dam fast and fast swimmers.
They are such fast swimmers!
Also, the dam serves as the beaver's fridge. They store food at the base of the dam.
It means it is a maple tree in the fall
It seems that it is a little more complex than that. Trees can produce yellow pigment without using any energy (the pigment is always present, hidden by the green chlorophyll) but the leaves must actively produce the red pigment. There are theories about why trees expend energy to produce red pigment and stress is one of them. This article explains what I am talking about: www.earthdate.org/episodes/why-some-trees-splurge-on-red#:~:text=Under%20stress%2C%20plants%20may%20also,a%20greater%20harvest%20of%20nitrogen.
It means it's a maple and it's season is fall
Evergreens are coniferous trees, their needles love about three years and they replace about one third of their needles throughout each year.
I mean, squirrels can literally grow and shrink parts of their brains when it's nut storing season.. animals are weird
wow, I did not know that about squirrels, very interesting. It would be cool though if somehow there were something that woodpeckers did that reversed the effect of brain I jury. This also would have potential to help with Alzheimer's
They do get brain damage but it doesn't seem to deteriorate. www.science.org/content/article/could-woodpeckers-teach-nfl-how-prevent-brain-injuries
They don't have special cushioning www.science.org/content/article/contrary-popular-belief-woodpeckers-don-t-protect-their-brains-when-headbanging-trees#:~:text=So%20how%20does%20the%20woodpecker,a%20human%20brain%20a%20concussion.
Outstanding scenery my friend, so nicely filmed and narrated!
Well I can't take any credit for the scenery. But thank you very much for the kind words about the filming and narration. I enjoy making these videos, it gives me great pleasure to hear that people enjoy watching them!
POGGER 😂😂
We were very lucky to be out on the water on such a nice day
10 minutes later all the mist had burned away, I was there at just the right time to capture this, so lucky! Blessed!😊
Let him be dude
I would normally agree, live and let live, but foxes that come to rely on humans for food don't survive in the wild (and can't survive in captivity very well) so I am trying to do this for the good of the fox.
I am just obsessed with taking pictures of reflections in puddles
You still have "whined up" windows ??
I haven't had wind-up windows for 20 years, and even when I had that car 20 years ago everyone mocked me for not having power windows. But here's the strange thing, I still say wind up or roll up the window. I wonder what people who have never known windows with handles say when they tell you to roll up the window?
@davepluscience - They say "put the window up" and "put the window down."
I was wondering if that was the case. Thanks
Ontario, Canada
It's a beautiful place to be. Not sure if you are aware but Ontario means land of sparkling waters in the language of the first Nations people who have always lived here. When you travel around this beautiful province that makes sense
I’m surprised the pjo fandom hasn’t found this yet
@@SmileMore-ui6hi please forgive my ignorance but why.might the pjo fandom be interested in this?
Oh,dam it,please stop!!
@@redino707 well frankly, I don't give a dam.
This is in Algonquin Provincial Park and it's a beautiful place to be. Sounds like I said Pod Lake but it's POG lake
This fox won't leave me alone. He thinks we're friends.
cool video man
@@sytheious123 thank you, I'm happy that you liked it.
Great video , such a peaceful looking place and nice and quiet thanks for sharing...
@@ShawnDownes you're welcome. I feel lucky to get to visit places like this and I'm happy to share. So glad you enjoyed it as much as I did.
I think that's a glass sea sponge
I don't think so! I Googled images for glass sea sponge, looks nothing like this! 🤔🤷🏻♀️
Not a glass sea sponge. Still in the process of figuring it out but I think it's a kind of fungus.
@@davepluscience that makes sense
@@atticuss8973 I will be doing a follow up video on the sample I collected so stay tuned.
👍
So serene, I enjoyed your appreciation for nature.
Thanks, I'm glad you enjoyed it. Being in such a beautiful place makes it easy to appreciate
Wow
Agreed, also very mysterious. There is so much we still need to learn about fungi.
It’s an un-lock.
That's very clever, I like that 😁
😮 coolio
Agreed, it was very coolio 😎
Awesome
Thanks, very interesting technology, it was a beautiful day to film as well.
Cool where is that?
@@darkhelmut7674 it's near Coldwater, Ontario, Canada on the Trent Severn Waterway. Lock #44
Would love to hear more on the ideal gas constant and where it comes from
I can do a short on that. The short of the short is that the universal constant is something like pi. If Pi describes the relationship between the circumference and diameter of a circle. Then the universal gas constant describes the relationship between pressure combined with volume and number of atoms combined with temperature in a closed system. I guess that was a little bit long actually. I will make a video about this. Thanks for watching!
I have made a video about the universal gas constant ruclips.net/video/kmp7bLkg4wY/видео.html
Tysm Mr.Plus! I was once of your students and I’m currently in uni rn, this really helped me for the high school review section in my chemistry course! I was so lost in the ideal gas law since our professor told us to learn it ourselves
That's awesome Gordon. I'm so glad that this helped. I'm working on making a library of these kinds of videos. Let me know if there's any other topics you'd like me to cover. Also, I am going to do an explorer video on this topic where I explore a little bit more deeply. The relationships between the left and right side of the equation

OK, maybe not a bike...

We gotta do this song up WAY BETTER though. This is like a rough copy.
@@davepluscience yeah true we need to re-record
@@2DeRonto it will happen my friend
@@davepluscience bet
That was extremely cool thanks for uploading so i can see this
@@IncriminatedAntelope you're welcome.
Your scale is way OFF. Thumbs down based on that. Polaris is not THAT close , as your model suggests. Put it further out and away, above.
Not to scale
Beautiful wording, hard to think of something we use to see as energy
Yes, it's kind of counter intuitive but we need to remember that objects do not have colour, they reflect the colour of light that hits them.
@davepluscience object do not have colour? *curls into exstitential ball*
Think about it this way: you can't see anything without light, therefore, when you see a color, you are seeing light. When you see an object, you are observing light bouncing off that object. Different objects absorb and reflect light energy at different frequencies. I know that sounds fancy, but basically all I'm saying is different objects reflect different colors of light and absorb different colors of light. A red object reflects red light, a blue object reflects blue light, a white object reflects all the light and a black object absorbs all the light. It's s not the object that provides the color, it's the light. In the dark, we would not see the object at all. I hope that helps, I hope it doesn't make you curl up even deeper into your existential ball. The world may be a little bit more complicated than you might have imagined, but once you start looking into it, it's also way more exciting!
1st question blue/clear/white/brown/teal 2nd Question depends on what water is doing
@@emilyshawayahamish7675 correct on both counts, if you want to know why water can appear to be so many different colours watch the video linked to the short (shameless plug)
