Rather than use Acetone to convert the plastic blocks back into a liquid, you should heat them up instead. A good place to start is around 325°F but it may be necessary to experiment to find out what works. Not all plastics melt at the same temp and you don't want to burn your plastic so start at a lower temp. Anyway, the blocks will revert back into a liquid but you won't foul up the plastic with the Acetone. With a heated melt, you also usually don't have to be concerned with bubbles either which is good. The smart play when repurposing the plastic into something like a handle for tools is to make a permanent mould that either fits together with the tool during the heat process or make a general mould to convert the plastic to square or round stock that can subsequently be shaped into a handle after the plastic rehardens. One of the best plastics to use for a handle is the caps from soda bottles. That grade of plastic is durable yet not brittle which means it doesn't like to crack or break because it has a little bit of flex to it. As for using the plastic caps, you don't necessarily need to cut them into smaller pieces but you might find it's better to do so if you have a small mould. Some folks cut them up with heavy shears or sharp wire cutters but attaining a spare kitchen blender can work as well if the blades are sharp. The key to success is making sure that the mould becomes 100% full during the melt and one of the best ways to do that is to heat the moulds in a vertical position so the plastic flows downward thus filling them. Some sources for sacrificial moulds to make bar stock are tin cans, glass bottles or even aluminum foil. After your repurposed plastic hardens, tin cans can be cut off, glass can be broken off and aluminum foil can be peeled off. The great thing about aluminum foil is that it's cheap and can easily be formed into a wide variety of shapes. With foil, you're only limited by the ability of the foil to retain the shape you form it into when you remelt the plastic... make too big of a foil mould without support and the foil mould may fail so keep that in mind. Ways to support a foil mould is to: - Use aluminum tape on the outside of the foil. - Use chicken wire for support on the outside or any other metallic mesh that will take the heat. - Manufacture a metal box large enough to hold the foil mould... and install the aluminum foil mould into Plaster of Paris and cure it before using the mould for a plastic melt. - Manufacture a metal box large enough to hold the foil mould... but install sand into the box surrounding the foil instead of PoP. As for the PoP, make a thicker mix and have someone slowly pour it into the sandbox while you slowly pour sand into the inside of the foil mould. The sand will act as a backer for the foil thus holding it in place as the PoP cures. Once cured, dump out the sand and load the mould with your plastic for heating. Note that using a sandbox can be tricky as the sand or PoP also may collapse the foil mould even after it's loaded... foil is thin and it likes to deform even if you don't want it to. You can combat unwanted deformation by using many layers of foil, however, if the mould is too big, the foil will still fail to hold the shape you desire which means it'll still require backing of some kind. Instead of PoP or sand, some folks have found success with casting sands (foundry), clay or heavy mud too but remember what you put into an oven may make fumes... fumes that you don't want to breathe or have smell up your house or shop. When using PoP, clay, mud or anything else that contains water then the smart thing to do is to let it dry out and cure before making a melt. You'll avoid fumes as well as steam which is a definite no-no... steam will cause mould deformation! At the end of the day, I've found the best permanent moulds are made from metals and are of the 2-piece design although multi-piece moulds above two parts can be made to suit your needs.

Я помню мы в школе(это было почти 30 лет назад), делали лак для ногтей😊. Линеек пластмассовых не было после этого ни у кого.

Felicitaciones por su creatividad, con las particulas de plástico, saludos desde Colombia.

Ну результат-то так себе, если посчитать стоимость шприцов и ацетона (может оказаться что и дешевле купить промышленно исполненные ручки), можно было бы отформовать ручки и поэстетичнее из чего-то другого самоотвердевающегося, или отлить из той же эпоксидной смолы в которую добавить можно всего что душа желает, в качестве наполнителя. Ручки получились пористые, мелкие, не ровной формы. И обрабатывать их пришлось, шкурить-шлифовать...Как наполнитель для прозрачного материала интересен, а так возможно хрупок из-за пористости... Можно слепок сделать герметиком или силиконом из любой удобной рукоятки и залить любой из отвердевающих материалов. Годится эксперимент, если остатки детского конструктора надоели под ногами и его срочно нужно извести...мешать надо тщательнее, тогда пузырей не будет и дать после размешивания выйти воздуху...Цвета классные, их можно смешивать и формовать скульптуры или декоративные вещи...Жаль, у меня не завалялось детских игрушек...Если пластик, такой пузырчатый и пористый мы в мастерской музея примешиваем карбонат калия после первой пробной отливки..., он тогда плотный становится, не рыхлый, не пористый...Идея повторного использования, творческое применение современных материалов и ваши эксперименты с ними , заслуживают бесспорно уважения. И берегут природу планеты от излишков мусора. Любопытно было посмотреть, процесс реализации идеи...Спасибо за подробное видео. Занятно!

The horror of seeing perfectly good lego cut into pieces to create really bad looking handles😱

Wonderful! Thank you. I'm wondering if the plastic can be injected in small amounts, then injected again to reduce the air bubbles...

Браво! Спасибо, что вы, очень честно делитесь своим опытом. Потому что сейчас, такие полезные советы, многие не делятся, а продают! Спасибо за честное видео ещё раз! Удачи вам, и в других ваших опытах!

Чтобы всё получилось юный техник. Как делали дети в юном технике. Пластик должен крошиться. Только из хрупкого пластика получается. Крошится на тёрке или в сступпки. Заливается ацетоном. И перевод супер-клей готов. А чтобы сделать какую-то рукоятку. Нужно добавить поташ. Стружку пластика, которая тянется Пэт. Плотный пластик. Смешивается и льётся. Застаёт. И можно обрабатывать. Супер-клей моего детства. Хрупкий пластик + ацетон. Ёмкость только нужно, чтобы она была постоянно закрыта. Ацетон испаряется, если остаётся просто пластик.стеклянный.

Do you think you could use silicone molds, like in resin craft? Thank you!

I wonder how much acetone to add in proportion the plastic. What if you soaked but drain the acetone before it gets absorbed? Just soften the plastic so it can be rolled into a dough ball then formed as you wish like clay and allow it to harden over time. Also wonder if some catalyst can be added with the acetone to accelerate the hardening so contact with air be unnecessary.

Wonderful. Thankyou. Can this be put into a silicone mold ?

Nossa incrível, desconhecia também. Obrigada pela dica!!+

You could cover the handles with resin to fill the holes and make a smoother surface.

vídeo muito interessante, muito útil, obrigada por ensinar, moro no Brasil

Great idea to reuse plastic ! Thank you !

Good idea can be very useful in many other applications.

Thanks for sharing 👍

Mantap... Ide yang sangat kreatif dan inovatif

Es muy importante conoser esta tecnica para plastico pero me gustaria saber si se puede hacer con otro tipo de plastico que no sean legos .gracias🌺🌷🌷❤️🌼💕💕🦜🌻🌻👍👍👍👍👍👍

Прекрасная идея утилизировать ненужный пластик. Браво!

I wish I could turn around my old plastic toys into something new and useful! 🔄🌟

Yes, acetone dissolves plastic! - And for the same reason it will also dissolve the syringes in a not very long time. So don't think you can store the dissolved plastic in the syringes for very long. - Also, in case you intend to pour the plastic into molds, you have to take into acount that as the acetone evaporates there will be some shrinkage due to the lost volume of the acetone.

Excelente idea, pero si debería golpear un poco el liquido para que salgan las burbujas y se niveles mejor el vaciado, también le haría una boca más pequeña al molde de los cabos. Excelente su proyecto mi querido amigo!!!

Super !❤

Wow they're very high tech and futuristic looking! The ergonomics are way beyond anything i've ever seen. I'm surprised NASA isn't banging down your door!

باسلام دوست عزیز من هم خواستم پلاستیک مایع درست کنم ولی مثل ساخت شما خمیر وروان نمیشه وبصورت یکپارچه به هم چسبیده راه حل این چیست

Bonjour quel est ce liquide que vous mélanger pour dissoudre ce plastique

Can it be preserve for a long time?

Pretty colours now your friends can tease you. Can the jars be reused for something? The plastice from the seringe can also be melted to serve as a glue. ❤

Awesome idea! How long can the liquid plastic be stored in the siringe?

Sirve la acetona que remueve el esmalte de uñas??

This is great! Is there any change.in hardness of the plastic after it cures? How long does it take to cure with large opening left to evaporate? Thanks and God bless!

Exelente idea.

Could place the file end into drill chuck and sand that way.

La acetona funciona en tapas de botellas PET?

You could have used plastic dip instead of waisting that much time. 😅

Que idéia maravilhosa qual outro tipo de plastico posso usar ? Eu não tenho Lego 😢 desde já agradeço ❤

The plastic that was used as molds. What will you do with it now?

Great job!

Feilengriffe gibt es fertig zu kaufen, wozu dieser Aufwand?

Very nice work but from where we can get Acitone

Felicito! Al Hombre Ingenioso que logró algo importante!!!😂🎉

how long did it take to cure fully?

how long is it possible to keep the mixture in a syringe. Does it melt?

Hey, what classification was the plastic pieces you used???

This has given me an idea of maybe using old CD cases. I don't have small kids with old Legos anymore. But I do have old CD cases not being used. I'm thinking this process would work for most hard plastics?

Когда тебе было 50, не было пластмассы. В 1981-1982 году восстанавливали линию связи телефона ТА-57(это сейчас не секрет) с помощью гудрона. Это был герметик, которого хватало с весны до весны.

I was wondering why everyone was being so critical about the finished product, till i saw it! I'm so sorry but that is the worst looking thing ever! I can't stop laughing lol I feel like I shouldn't post this but it's hilarious!!😂 On a serious note though, thank you for the idea. I think a lot of people will actually appreciate the creative opportunity that you provided us with. Please don't take this the wrong way and thank you again, sincerely.

Здравствуйте! А можно ли, точно так же, таким образом расплавить стекло? Спасибо за ранее за ваш ответ!

Muito legal qual é o líquido usado p dissolver o plástico?

Could you inject this into a silicon mold? Or will the acetone ruin the silicone mold?

Where you can buy acetone?

What's likwed name? And where I can get

Этому секрету, как у нас говорят сто лет в обед, и далеко не все полистиролы растворяются в чистом ацетоне, да и с формой не зачёт ))).

Amei!

Joaoal es.gistei belo trabalho.❤❤lindu.

Me encantó que buena idea súper ❤

Oooooo-kaaaaay, but Lego sells for a small fortune on eBay, so how about we substitute those Lego pieces with soda bottle lids?

Super video🎉

Идея неплохая,но в качестве ручек больше подошла бы полимерная глина

Great idea

Es. la. misma. acetona. que. se. usa. para. las. uñas?????.

Thermoplastic is much easier to process. It is also liquid at 60/90 degrees and can be shaped and heated again in warm water until the shape is right. Much simple and you don't have to wait long before you have it liquid or solid/cold.

Great use of reusing Plastic, in this case, Lego for the colours. I like the idea of using a Syringe to add to a mold, How long will the plastic stay as a liquid in the syringe. ?. Also maybe make a Proper File handle mold using Wax (Which can be reused). Also make the Liquid Plastic thinner so that it forms Better. I know Buying Handles would or could be Cheaper but knowing how you can make them is brilliant. Making a proper mold would be an interesting Video. Well done

Enjektörlerden çıkarılmadan da kullanılabilir sanırım. Biryığın sapı kırılmış biçagım var en kısa zamanda deneyeceğim thankyou

Can I use liquid plastic for making fiber cotton?

How can we get rid of the bubbles?

Lo tomaré en cuenta, en mi país acetona pura no se consigue en todas partes y un frasco chico cuesta como 3 dólares

ماهى المادة المستخدمة لتسيح البلاستيك

Or a mold then put it in fridge it should come out easily from mold I’ve done it with silicone glue and color sparkles for your nails put wire to make bracelets in form of heart and a pendant made came out nicely it was a first time experiment because of the silicone glue I figured it would form nicely paint or nail polish can be used as well 🤷‍♀️🤦‍♀️🤷‍♀️🤦‍♀️🤷‍♀️

could someone tell me why the glue doesn't work for me??? the plastic stays solid on the bottom of the jar and the acetone is not dissolved in the plastic. i tried different acetones and it doesn't work. is there anything else going on?

What chemical do you add to the plastics

Buenisimo!!!!!!!!!!!!.

Well...great idea in theory BUT Legos are what too expensive to do this w them! Substitute w a cheaper plastic😮

I wonder what number plastic are legos and if I can use other plastic I have lying around

Y cuando está derretido sirve para pintar manualidades?

ايش نوع المادة الي انظافت اليه

Will acetone do this to any plastic? Like bottle caps

👍👍👍

Esta bueno el trabajo pero el terminado está muy poroso en un torno quedarían mejor

Cuanto tiempo dejar secar?

Hubiera sido más fácil quitar el tapón de la jeringa y verter el líquido por arriba.

надо его сделать еще больше текучим как масло и пузырьков не будет и шлифовать почти не понадобится

What is the name of the liquid you put

ممكن ان نستعمل اغطية للقارورات؟؟؟

Wil this work for any plastics ????

Надо было не снимать колбочку от шприца, а просто удалить выступающие, лишние части. Выглядело бы более эстетично и ручки остались гладенькими.

hi, is plexiglass ok?

con tapas de gaseosa es mejor o rexina epoxica genial te salen

اسم المادة اللي بتسيح البلاستك وشكرا

I was just attempting to cut plastic this way last week and cut the entire top of my thumb to the bone. I almost passed out before i got an entire dollar store bottle of crazy glue on it so i didnt loose anymore blood and could drive myself to the hospital.

هل تنفع هذه الطريقة مع جميع انواع البلاستك

شكرا للمعلومة ممتازفيديو مفيد جدا

How to harden them again?

Excelente

Для автора данного ролика развивающая информация. Инструменты- ручки на которые вы делали, называются надфиль а не фаил.

Parabéns

Очень интересно ❤

я это делал еще в конце восьмидесятых, когда в школе учился. Литье получается очень корявое, много пустот при высыхании ацетона. пойдет только длятонких слоев, а толстый больше сантиметра будет сохнуть много дней

A nyél feltöltését nem így csinálnám! Nem vàgnám fel a fecskendőt, hanem ahol a reszelő be van dugva, ott fúrnák egy lukat és a másik végén mégegyet! A reszelőnél benyomnà a fecskendőt a műanyag masszával és bele nyomnám, hogy a másik végén kifollyólan. Ennyi.
