InstaMorph Reusable Moldable Plastic | Thermoplastic Beads, Meltable Polymorph Pellets | Lightweight Modeling Compound for DIY Crafts, Sculpting, Cosplay Accessories | Temporarily Repair | White, 3oz

I purchased this on a whim as I was restocking some hardware and glue and it came up with great reviews. When it first arrived I thought I would just try it out to see how it worked -- since it is supposed to re-useable it wouldn't be a waste and if it didn't really work as well as everyone said then I could return it. It was VERY easy to use. I put 1 cup of water in the microwave for 1 minute and my digital thermometer read almost exactly 140 degrees (I have tried it since at even higher temps and it still works great -- just test the water temp before plunging your hand in!). Once hot I dumped in 2 tablespoons of the little beads waited 2 minutes then picked up the rubbery lump right out of the water and started forming it. It was very moldable (and fun) and set up hard and strong in about 3 minutes. But that was just testing it out... The "Very Handy and Surprisingly Effective" part came later when my wife asked me to fix her toilet? The plastic nut that holds the handle had cracked and while the company graciously said they would ship a new one for free, they also said it will take several weeks. Several weeks without a flushable toilet in the Master Bedroom isn't an option so, I heated up a cup of water and dropped in about a table spoon of InstaMorph. Even 1 tablespoon was more than I needed, but one of the great parts about this stuff is you just put the unused stuff back - no waste. After 2 minutes in the warm water I took it out and formed it into something like a gummy worm, about as thick as a straw and 2 inches long then simply wrapped it around the threads and squished and formed it a bit to make sure it got in deep. A couple of minutes later it was HARD PLASTIC and holding on very tight. I used pliers to un-screw it and looked in amazement at this perfectly formed replacement nut (I could easily have used a crescent wrench to make flat parts for tightening too). Looking at it installed I realized I probably won't even need to put the replacement nut on when it comes. I will try to use that moment as a reminder to come back and update this, but know that if I haven't updated this yet, then it is probably still working. Clean up... none. No mess or fuss, just dump the water (it is all non-toxic) and put any leftover bits away to reheat and reuse later. I did decide to form them into several long strands instead of one big lump, though, just because they will heat up faster and it seems like a useful shape to start with. Net conclusion is that I'm really impressed with this stuff and recommend that everyone have a little bit around for quick fixes.

InstaMorph is an interesting, if slightly finicky accomplice for all sorts of unexpected uses. The container yields BB-sized balls of mostly opaque white plastic, similar to the appearance of the robot skin in I, Robot. When dropped in a bowl of hot water, they'll turn transparent within fifteen seconds and stick together (and to the bowl). You can then drain the water and prod the resulting soft and sticky mass onto any wet surface to mold. The plastic doesn't retain enough heat to burn. Molding properties are similar to modeling clay. It's very easy to join and smooth edges with your hands or flatten a piece as if it were cookie dough. You can manipulate the shape for about three minutes until it begins to harden. It'll take another ten minutes to reach final hardness, or you can speed the process by putting it in the freezer for a few minutes or running it under cold water. Beware: InstaMorph gets extremely tacky once it begins to set. If you're molding it on surface that it's not supposed to stick to (e.g., the batteries under the battery door cover I just made) and you make a mistake, don't attempt to pull it off while it's still partially pliable. You'll just leave a plastic residue that'll be almost impossible to remove later. If you wait until it hardens, it'll come off in one piece and you can start again. When totally hard, strength is similar to standard, non-specialized toy plastic. It is not at all brittle and will bend under load. While you can cut very thin (under 1/16") sections with scissors, it's almost impossible to tear at any thickness. I created a simple tube about 1" in diameter and 1/8" thick and was able to stand on it with minimal deflection. You can't weaken the material with handling. Even concerted rubbing doesn't put enough heat into it, though a fingernail can scratch it. If desired, the final product can be painted or epoxied to other surfaces. It's best not to store remnant pieces in thick shapes because they'll take much longer to heat through. Just make a thin pancake and cut it later with a pair of scissors. The only negative of this product is that it has a noticeable, albeit subtle, scent. Handling will convey this scent to your fingers. I wouldn't go so far as to call it a residue, but any smell at all implies at least some material transfer. Given that the FDA approves medical grades for use in the human body, I'm not terribly concerned about health consequences, though I probably wouldn't attempt to microwave this product.

I used these to make fangs over my natural teeth for cosplay, and they worked very well! Following a tutorial for whatever you're trying to make is what I would recommend :)

I bought this to make a plastic windscreen for a digital voice recorder (DVR) I sometimes use while riding a bicycle. I found it very easy to draw on a piece of sheet metal the outline of a flat sheet shape that I would eventually bend to fit my DVR. I then placed the pellets on the sheet metal, to fill the outline, and placed the sheet metal over the top of a pot of boiling water. In a few minutes the pellets became clear, indicating that they are soft enough to mold. I could then add pellets where I had any areas not well filled by the initial bunch of pellets. Once the flat shape was done, I put the sheet metal and InstaMorph shape into the freezer. A few minutes later I found that the InstaMorph released easily from the sheet metal. Next I heated a measuring cup with water to a temperature of 150F. I dipped the InstaMorph sheet into the hot water, waited for it to turn clear, and then wrapped it around the DVR (covered in plastic wrap, to avoid water damage and possible adherence by the InstaMorph). This all worked very easily. I later warmed the InstaMorph windshield to flex it enough to have the desired friction fit to the DVR. It has reduced the effect of wind noise on the voice-activated microphone of the DVR. The windshield in plenty sturdy, too. I recommend this product for such applications and look forward to other needs I may have for it in the future. When melted it is like modeling clay that will make a reasonably strong plastic part when it cools.

My daughter uses it for coz play, but it has many other uses. Best poly morph, it does not crack after reheating multiple times.

I made a fake front replacement tooth. Works like a charm! Saved$1500 at dentistry

Got this to make a small part for my camera but I'm sure I will find other uses for it. Highly recommended !

I bought this to make lil fangs (I got influenced by tiktok AHAHA). It is very easy to use but tbh I only used it for the fangs and got bored after a while since I don't do cosplay LIKE THAT. I will prob use it again one day but tbh it just sitting there collecting dust LMAOOOO. ITS GOOD THOUGH. GO GET UR FAKE VAMPIRE TEETH YALL

Excellent just as described!
