Copy esigning record

in today's video we're going to test out if it's possible to make a playable record out of candy [Music] guys a while ago I did a project that I thought was a ton of fun seeing a few could pirate music by physically making a copy of a music record to do that we took some silicone rubber poured it over the whole record pulled the mold off and then we cast resin onto it the result we got wasn't the highest quality sound but it did work the mold and cast of the record was still playable on our record player since then and currently and suggested by dozens of people in between then and now I've wanted to try this using candy instead of using resin casting candy into the mold we've had some difficulty casting candy into silicone molds before it has a tendency to bubble quite a bit and if there's a lot of bubbles then you're not going to get a good playable record I do have a slightly different kind of silicone that I've done some small-scale tests on and it seems to work pretty well I think doing that along with avoiding adding any flavoring or coloring into the candy should help minimize the amount of bubbles that we have in there I'm gonna have to be pretty careful because even really small bubbles would probably throw the needle off massively and then we would not get a nice smooth playback but I do want to try it so I've got this is called sort of clear it's just one of many types of silicone rubber made by smooth on and they recommend using this for candy casting so I want to try it and see if I can get a good result first step is gonna be taking our record mounting it to the desk a little bit building a wall around it and then we're gonna start mixing up our silicone and pour it over the record now we do need to make sure that our record is actually working before we mold and cast it so we're just going to give this a test [Music] last time we did this we did have several people complaining about the quality of our record player yes this is the cheapest one I could find I'm not going for the high fidelity music experience and literally just testing if it plays or not all right so our record does work it does play that's really all we need to know so now let's try to make a mold of it so I've got the record down on the table I used a little bit of double-sided tape to hold it in place and make sure it doesn't like try and float up above the silicone now I'm gonna be using this oil-based clay as a barrier I'm gonna put that all the way around the record up against the edge so silicone can't steep underneath it and then as sort of a wall as well so that when we pour the silicone it can just sort of fill on to it now I'm pretty sure what I have here is a sulfur free oil-based clay it's definitely oil-based it's the kind that doesn't ever dry out and that says that right on the packaging non hardening reusable won't dry out so that means it's an oil-based clay [Music] [Music] we're actually just gonna use our vacuum chamber as a mixing container because I do want to vacuum this stuff but if it's like other silicones it's going to expand a lot and frankly the best way to have all the space we need for it to expand is to just use the chamber itself it's been pretty well washed and cleaned since we last used it and it's gonna be a little bit awkward to mix it in the container but not too bad a lot of the time the catalysts and the silicone are different colors or even the two parts of the silicone are different colors so you can easily tell when it's thoroughly mixed here we've got kind of clear and kind of clear so slightly mixed and very thoroughly mixed look pretty much the same so I may be over mixing because if it's too mixed it will cure well if it's not mixed enough we're gonna have a lot of it not here or at least not here quickly but I think we're about there so now we're gonna throw the lid on this thing try and get rid of all these bubbles and we'll let the pressure back in and then do it again [Music] this time we'll let it sit at the full vacuum for like five or ten minutes to really get out as much of the bubbles as we can now there's still bubbles in there but I think we've pulled out about as many as we're gonna get just by using the vacuum chamber this is a fairly thick silicone so it doesn't like to fully D gas we're now going to try and pour it slowly onto the record and then I'm going to go through and try and take out bubbles individually [Music] you can see that there are still bubbles in the silicon most of those I'm not concerned about if it's not touching the surface of the record that's fine there can be bubbles in the middle of it if there are any bubbles that are on the surface of the record that I'm concerning so that's why I got this razor blade anywhere that I see bubbles I don't know how well it's showing up on camera but as I move this the bubbles are actually casting sort of a shadow inside the silicon if I have anywhere I can't see a shadow that's a good sign that it's actually like touching the record down below and I want to make sure to try and take those out roll I'm pretty happy with this this is looking quite good and now we're just let this cure overnight to make sure it's really solidly cured I might hit it with a heat gun to try and pop some of the surface bubbles just because that way when we flip it over to cast into it it will be flatter we have now let the the mould here overnight good test for if the mould is cured is to just peel it off of whatever container you were mixing it in this will also show me how well I mixed it up if there are spots in here where it's like staying all gooey and goopy that means I didn't do a good job of stirring it in those places oh yeah that came off really nice whoo all right so that should be good now we get to the mould on our record here [Music] is beautiful I do not see a single bubble on the surface very exciting alright that is about as good of a mold as I could have hoped for I am very happy with that I'm just gonna do a quick trim around the edge to make it lay a little bit more flat the surface tension where it was in contact with the clay will have given it a tiny bit of a lip in some places and that will make it sort of dish down a little bit and that really shouldn't ruin anything but if I can eliminate that it should be so much the better now we need to cook up a batch of hard candy we're just gonna be using our normal recipe which is 2 cups of white sugar 2/3 of a cup corn syrup and 3/4 of a cup of water to cook that all together until it hits the hard crack stage on a thermometer and we're gonna let it cool down a fair amount so that all of the bubbles leave the candy and I think it's at the higher temperatures that it really reacts with the silicon and gets more bubbles and we don't want that so we are going to let it cool down a little bit but it should still be runny enough to flow nicely into all of the grooves of the record I've let the candy cool down after cooking so there's really no bubbles in it anymore I am gonna do a little bit of a test just pouring a tiny bit of it onto the center of the mold where there's no track no part of the record that will actually play and I'm gonna see if it looks like it's bubbling up and if it isn't bubbling up then I'm just gonna keep spreading then just try and get the candy to go all over the whole record there are some bubbles in the candy but it doesn't look like it's forming bubbles in contact with the silicone so I'm just gonna see how well this works [Music] that's what I was afraid of there we go getting lots of bubbles on you now alright with our first attempt the we got a lot of bubbles and I think it's because when the candy is thick it stays very hot and that heat is what's causing the bubbles so I've got this cold stone slab and I'm gonna try and cool it off using that but also I'm gonna try and have it at a sloped angle so as I pour the candy on it will run down more and by doing that I hope you'll stay thinner so there will be less heat in the candy because as it's thin it will cool off faster okay this record has all sorts of bubbles and cracks in it but I still want to see if we can get any playing out of it even just for a few seconds before the needle hits a bubble and freaks out [Music] apparently the grooves in this are are too intense and they're driving the needle sideways before it even gets a chance to play alright so I don't know if you can hear it through the static there's like 95% static but there is 5% music coming through the static theoretical proof of concept we do have sound we do have the music coming through a little bit it's just figuring out how to actually get it to not bubble on the record so we get a clean cast of it [Music] well I would not call this a resounding success we did get a little bit of playable audio on this first one here it's not great so I would not say we've had a resounding success but we didn't show a slight proof of concept so I think this is something we're going to revisit in the future there's got to be some way to get perfect bubble-free castings of sugar on silicon if you know anything about that please let me know the best results I've had are when the candy stays really thin and doesn't puddle up but I have a very very hard time getting that thin of a layer of candy to go down on the record I think it has something to do with the heat off to experiment with that I don't know if it would be better to heat the silicon up so it's closer to the candy temperature or to cool it down so that maybe it causes the candy to solidify before it has time to form any bubbles there's a lot of things that I can try this is version one hopefully we can revisit this in the future hmm boylee candy guys that's it for today but you know we've always got more for you to see click that box up the top to check out our most recent video and we'll see you the next one talk to you then [Music]
