 Welcome back to Kids Fun Science. My name is Ken. Today's experiment is the Pringles Ring Challenge, also known as the Pringles Circle Challenge. So basically no glue, tape, anything to hold it together besides friction and gravity. So at the end I'm going to have one of my friends from Science with Vexi. She's going to explain the physics behind it very easily and I'll have a link in my description and to be able to point you where you can get that information. Alright, so today's experiment is we're going to make the Pringles Loop, right? So we're going to make a complete circle with Pringles, no glue, no tape, nothing. Just the Pringles itself and the gravity and the friction that holds it together. I'm going to try to do it kind of like what I did with Leonardo's Arch Bridge. I'm going to do it with the Pringles, but try to do a complete circle. So I've never done this before, though I did buy the generic brand trying to save some money. And the generic brand where the Pringles are arched more, which is going to help me here. I'm assuming the other ones were straight, the non-Pringles. And even though they're the same shape, they weren't, they were flat. So I never got the arc and so it did not work and so that's why I'm trying the Pringles now. So I think the key to this is going to be building a nice base so I can support the friction coming up on the side. So this is in fast forward mode. The hardest part was trying to get that base going. As you could see, I had to restart here and once I got the feel of what the base was like, then I started going forward. I started using two at a time, which worked really good for me as I used one and then laid the other one halfway over it. Kind of like the center of mass holding that other one so it would arc up on the ring to be able to make those walls go up. I also had to continue to add the base as it started to tilt or started sliding sideways so I was continuously adjusting it so it wouldn't tip all the way over. It's not as easy as it looks, right? So now I was about halfway there. I switched from putting all the chips on the bottom inside to like some on the inside of the chip. So I was splitting the chips open and kind of sliding one down in between worked really well as it slid down. The friction would hold it together, which made it work a lot better and allowed me to go the height I needed to go to complete that circle. It's not a complete circle, but I was able to get it to go all the way around, which is pretty cool. Here it is a little bit closer. You can see my base is pretty big. You can see the sides on how they were sliding right into one to the other, which is pretty cool. Alright, so to try to figure out the arc on here on the Pringles itself, the radius, right? We're going to measure the inside. So when I take this and measure it, it's about 11 centimeters in diameter, right? Which is going to give us a curvature here on the radius so to be able to figure out what the radius is. And so it's probably around about five and a half. And now, of course, this isn't a perfect circle, so it can vary on that. It's a good guesstimate. But basically what it's doing is when you put down the Pringle, it's basically saying the first one could be about the center of mass. It could be about that far over. And then as long as you keep going, it'll go a little bit shorter each chip, which gives it the, and then when you get the weight in there of putting more in the middle, it's able to extend it all the way out and it continues to do that. And as it gets up to the top, then you have these two chips here. And when you slide one in between, the friction from the back chip and the front chip are pushing against it to hold it in place so you can continue to go around, which is pretty cool.
