De-Bonding CA Glue

George Vondriska
Duration:   6  mins

Description

George did an experiment in the interest of science. He glued a couple of his fingers together with CA (cyanoacrylate) glue. He did this because Titebond Bob said he could get his fingers apart by soaking them in water. What?! Water will dissolve CA glue? Spoiler alert. Water won’t dissolve the glue, but it will allow glued together fingers to come apart.

As you watch the video and see how long this takes to work, keep in mind what Bob keeps saying over and over again. George put A LOT of glue on his fingers. If there had been a more realistic amount, like just a little dab, this would have gone a whole bunch faster.

    I will admit that I scrolled through the timeline once I understood what George was doing to when (if) his fingers would separate. Wow - 25+ minutes! But at least it did happen without causing damage. Thank you for the video.

So this better work. I was, I was today years old when I learned from type on bob that if you glue your fingers together with C A glue, which I just did normally you would do it accidentally. He says if I put them in water to tell me again while this is curing, what's going to happen? What is the water gonna make? Yeah, this is so counterintuitive to me, but I'm doing it anyway. Ok. So, so the water will swell your fingers and that's why it causes them to the skin on your fingers. And that's what causes. Ok. So just fy, I, I'm glued to, I'm currently glued to get, I can't separate my fingers. I'm glad I did this. My finger is not my eyelids, by the way. Ok. So I'm in a, in warm water. Ok. So, so the water will absorb through the skin causing your skin to swell as it swells. It's, and the glue does not, it's will slowly pull away from the, from the glue. So, so again, how long that takes, uh, may be the issue, right? It's not just swell yet. So what I'm doing in the water is, I'm just a little bit of outward pressure and I don't think I've pulled any skin off yet. No, you won't pull the skin off. It may take a little while to, to, to, to get, how long does it take to get the little folds of the skin? I haven't been in a, I haven't taken a bath as opposed to a shower for like decades. So, I don't know when my skin gets pruny. All right. So how the C I glue works? You, are you ready since we're, you have a captive audience? That's right. So, as the um inhibitor breaks down, uh the acid is neutralized, uh a hydroxyl group is formed which has an extra electron on the end and on the electron will then move through the double bond, which are cocktail parties. What? And then as that electron then zippers on and builds others on top of it, it can go pretty fast and each one is a little bit exothermic, which is what can cause the heat to generate. Are you gonna fall asleep? Yeah, I'm, I'm, I'm, this is great because I was looking for an afternoon nap. So I'm pretty close now. But anyway, it's so as I pull, like at the very edges, it just started to separate a little bit but not, you know, they're not readily just, it, it won't do that. It'll slowly as, as the water absorbs on the outside of the sea. Igloo and then moves to the inside. It'll start, it's separating more and more from the outside in and I think I'm 30 seconds away from having them apart apart. Maybe. I hope, I don't, you know, shatter the glass with my super finger strength when they pop apart. But yeah, it's, it's interesting how I can feel it giving, it's the wrinkly skin effect and it might not be 30 seconds. It might be more than that. So, Bob, how, how do you know that this works or do you know that this works? We have had anecdotal evidence of that. That, that is the safest way of doing that. Um, I mean, you can use acetone, you can use fingernail polish, but those can be kind of harsh chemicals and acetone is tough on your skin. It very, it decreases, it quite, quite quickly, um, causes it to dry out. Um, the nail polish remover which you can use does have some oils in it to, to replenish your skin oil. Um, but again, you're, you're talking about Beyl acetate and, and, uh, a, it's kind of one thing for people to put that on their fingernails, which are a rigid surface as opposed to intentionally putting on your fingernail, finger, nail, polish remover on your skin. But, but you desperate times call for desperate measures did put a lot of glue on that one. I did put a lot of glue. You, you keep telling me to only use a drop and I'm so bad at following your e so for people still watching and not to off, thank you for still watching. I'm not quite ready to take a knife and cut my fingers apart, but like there was a distinct, I don't know, sort of puckering apart that was happening and then it kind of stopped, like, literally when I said, I think there's 30 seconds to go. They were really feeling like they were coming apart and that's probably the edges that were absorbing that. And then as you pull it apart now it's, and it has to absorb the water again. So because the glue itself is water, water resistant, water resistant. I mean, you can put that, like I said, I've got a film of that under water to determine if it swells or anything. Um It's been underwater for 12 years and has not moved. So this took a long time. But what do you keep saying to me over and over again? You used a lot of, a lot of glue. So realistically, I think if somebody was accidentally dabbing their fingers together, there'd be like a tiny spot of glue on there, not a quarter size chunk of thick glue. Um And the good news is, I mean, you can see how my fingers are kind of puckered. Um So it's, as you said, it's that puckering, it's an expansion contraction thing, right? Pull it away. So it works um it takes a while but it's good to know that it works and it's good to know that water is benign and will open this bond safest way to do it. Yeah, gives you safety. So um thanks. I think um I could, I could rob a bank right now because I have no thumbprint. Um It's covered with sea igloo but um thanks I think for the tip. You're welcome.
