Speaker: It's time again for another addition of Spangler science. Steve, this morning you are going to show us the floating water trick, and it depends if you don't mess Steve, what is this?
Steve Spangler: No, no, no, it's okay see you are learning that whenever the water comes on this -- you have dressed perfectly so don't need to worry about it. Alright, we are going to go from very old to modern day, I think you will enjoy it. grab that Erleumyer flask, I'll show you how this works. So a little bit of water goes inside, and then this is a classic air pressure demonstration, which is kind of fun. So here's what happens, you take the playing card, ready, and so, you put the playing card on top. This is the best part. Now you turn the whole thing upside down, got it, it's okay, turn it upside down and now if you paid your due in the local science club, you can let go, just very very carefully and the card should stay right there.
Speaker: oh!
Steve Spangler: Can you do it?
Speaker: Yup.
Steve Spangler: You may have a little bend, so if you got it, voila! Now, about 15 pounds of pressure pushing up if we were at sea level, about every square inch. So it's amazing for kids to be able to see, as long as the water doesn't exceed that 15 pound mark, then the air pushing up right below that card will get it, just break free like this, ready? You got it. Fun to do at the dinner table, but not many people have erlenmeyer flask over the dinner table, right? So let do it with wine glass, alright,
Speaker: Alright, alright, okay.
Steve Spangler: So here's your wine glass. Let me show everybody how it was originally set up. You take a men's handkerchief and you would cover -- clean of course, and then you cover it, and then you'd pour water through it just to show people that water went through the handkerchief like this. You can take your handkerchief if you want to and cover it up. This is just a classic, like from, I don't know, maybe the 1800 or so. So cover it up like this.
Speaker: Does everything just have to be damped like this?
Steve Spangler: Yeah, yeah, so most men carry a damp handkerchief, alright? Now put your hand on top like this, got it? Turn the whole thing upside down. Now this is very very cool, now slowly put your hand away and the water stays there, isn't that fun? And you can slowly just peel this away ,and it will stay there. Now this is not air pressure, this is actually water hooking in between the little fibers, there to form surface tension, isn't that pretty? And then all of a sudden you just pull, and you've got it. Isn't that's great?
Speaker: Oh! That's great.
Steve Spangler: Look at the fun. Now you get this version and you have -- no, no, you didn't go wrong at all. The air pressure that's built up inside, that's kind of cool, just stay there for an hour and it will be fun.
Alright, I'll show you the last part, watch this, you'll love this, watch this, ready? This is modern day, water goes inside like this, ready? And now, if you are careful, hand on top, turn the whole thing upside down and watch this, ready?
Speaker: Yeah.
Steve Spangler: Gone.
Speaker: Amazing.
Steve Spangler: Is that cool, it's really not that amazing, there is just a sponge inside, and that's absorbing it, we don't really have enough time to take about that. You tell me about the website --
