Karen: Alright, ketchup, the main ingredient in today's Spangler Science. Mark is with Steve, who doesn't -- just love to play with food.
Mark: We love to play with food
Steve Spangler: You love it.
Mark: Most specially ketchup.
Steve Spangler: I lived in college on ketchup and salting crackers. So are you ready? This is not a science, this is magic. This is pretty amazing. Alright, so watch this, you just take a ketchup packet and you put it in the bottle like this. So here's a bottle of water, don't even try to figure this out. Now this goes down inside kind of like that, beautiful, and it floats, because it does everything on 9news. Alright, you got it.
Mark: There we go, does it work? Yes, it does.
Steve Spangler: Alright, so here we go. Now we're just going to cap it off, alright. Now I am going to hold to this Mark and you will not believe this, ready, so when we hang on to it like this. watch this, through the power of my mind, it's just going to -- watch this, ready, fall, oh great ketchup, look at that, now watch this, you can give a positive command, rise, oh great ketchup. Now I know that you can't figure it out, and you can't even see the little thread there, can you?
Mark: No, ha ha ha.
Steve Spangler: Alright, I'll teach you how to do this, because nobody would have ever thought you could do with ketchup, and then can I'll kind of show you the ketchup secret, okay?
Mark: Okay, alright, but I know to do this with the little Cartesian diver.
Steve Spangler: You are so smart, see after all these years you should have put a science store. Alright, so the classic was, using these, right here, with an eye drop, alright, a medicine dropper. So drop a medicine dropper in water and because it's glass, now if you use a plastic one, now the difference -- see how it floats. Can you?
Mark: Yes, it floats.
Steve Spangler: So, you can actually cause it to just barely float. So just hold it here like this and squeeze a little of the air out and let go, and it will just kind of barely float, yeah, not not too much at all, just kind of let it, oh, nice job. Alright, so now here's what we are going to do.
Now take a one liter bottle -- and these are easy for kids to squeeze or if you are doing this at home, it's a little bit easier. So open it up like this and now carefully, with the water loaded inside, you're just going to drop in the bottle. Nice job, now wait just a second, I need to tell load you up with some of the water here, absolutely. So we load you up with water, so now you have the makings of this great physics little experiment, called Cartesian diver, named after René Descartes. I know you are concerned, alright. So now hold on to it like this, alright, let the camera kind of get in close.
If you notice, if you squeeze, you can actually make the water level go up and down inside. See how it goes up and down, because you squeeze. Let's just see how it holds, so the sink is because you are squeezing, look at that, because you let all the water comes out, so it's like a little submarine, so as you squeeze down, it usually go up. So it's Cartesian diver, kind of how a submarine works, but, the ketchup is a completely different beast, right? Because you can't just push water into the ketchup. So the secret with the ketchup is, you have to find ketchup that just barely floats. So while you are sitting at the dinner table and you have nothing else to do, you just in your glass of water, just keep on throwing ketchup in. Take the ones that float, you are set, alright. So you notice how just this kind of -- that's a perfect way, it just barely floats. So take your bottle, get your bottle here.
So now this is a very very cool thing, you are now just changing the density of it, but you are doing tat by squeezing the little pocket of air that's inside the ketchup packet. Now, viewers will be thinking today, I wish I could have learned something about ketchup, but I just -- Steve didn't come through, but there you go, you have got it. So this one will go here, and mind that now you are set. So now when you squeeze, and of course, you can't let anybody know that you are squeezing, you are actually squeezing that little pocket of air.
Mark: That's right, amazing, because they can't figure out how it is? That's your actual --
Steve Spangler: So you just have to sit on your desk, so when people come by, you can say the amazing ketchup trick and squeeze, and watch will happen when you squeeze. Now, I'd like to end it this way, watch this, you just reach up and you pull a hair. So you watch this, you'll, ah! You pull a hair and then you can wrap it around the ketchup, and then you pull down, and that really messes with the kids who are in first to second grade.
Mark: I know the basic, how does he do that?
Steve Spangler: This is going to mess with the producer too, so that's a -- alright, and you just kind of pull it off like that, boom! And you have got it.
Mark: Does it floats? Yes, it does.
