InstaMorphReusable 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.

In 2017 (now 2023) I bought the larger bag. At first, I was a bit clueless on how to work it. However, soon I learned to heat a cup of water (a coffee cup) about ⅓ of the way full with water. Withiut any product, put in your microwave for 1:10 to 1:20 depending on wattage. The waree will boil. In the meantime, place a small amount or even larger amount of the pellets on a metal spoon. When the water is done, slowly lower the tea-spoon into the water until the spoon hit the bottom of the cut (guide spoon along the inner wall of the cup). You'll see the pellets begin to float away from the spoon and them very quickly turn from white to clear. Usibg that sane spoon once the pellets become clear, lift the now adhering pellets out of the cup and mold them into whatever shape you need. Need to replace a tooth? No problem, as this will slowly begin to harden while it cools, approx 20 to 25 seconds and beyond it becomes harder, still. So be sure you have drying (now blob) pressed hard into your space, veing sure to anchor the blind if melted plastic into whatever gap you have AND the anchoring teeth on either side. You can't stick something to nothing, therefore wherever the gap is, use the adjoining teeth as anchors to keep your now sold hardened plastic in place. You want to be sure you've pressed hard during the drying process, this helps assure a tight, longer lasting bond. You also want it to be flat as poddubke and that you've ever so slightly bitten down to assure your other teeth are aligned and that the now mold it's higher than the others or, it'll be very uncomfortable for you after mold drys. You'll learn over time that if you don't get it right the first time, (maybe because you didn't "pat dry)" (this helps) the melted pellets before putting them in their newly empty spot (your mouth) or not using enough or even too much, you can always re-gear water and using the very sane pellets which are melted, back into boiling water and try again. Eventually, you'll get the hang of it. While it's drying in the mouth, place & keep continuous pressure on the drying plastic to assure the best adhesion. Be sure yiu dry your fingers every couple of seconds initially, this will help you to keep mold into place and it will aid in drying. I got the bag in '17 and it's still more than half full. If done right, and you're careful, each new mold you've made ought to last a few weeks to several months. You'll never eat an apple even after the mold is completely dry, if it's a front tooth. However, if you remain mindful your mold is strong but is only a temporary mold, You'll be able to eat most anything. I've repeated this process in the same spot, for 5 years. Amazing stuff, you won't regret it, especially of you use it correctly. With 12 years on Amazon, I write very few reviews. This one, was worth the effort.

Needed to use a joystick left handed but the hand rest is on the right. Looked through lots of model plastic options and reviews and chose InstaMorph. Created a small frame out of wood on the joystick, melted a small amount (not knowing how much I needed) and pressed it into place. Very easy, very pliable, quite solid though like 'heavy jelly'. Needed more, so melted more and just added to the existing.Left to harden and was delighted (and pleasantly surprised) with the outcome as InstaMorph had also stuck to the joystick itself - I had planned to screw it on once hardened but not required.After trying out, the shape was raised a little too much at the back. I tried sanding it down and to smarten up the sides but the small electric sander generated heat I guess as the plastic just became congealed. So used a hairdryer to heat up the area I wanted to smooth out and once hot I could flatten it with my finger.Then painted it just because I could. It's not pretty but it's 100% functional and exactly what I needed.First time posting pictures but with the different feedback in the various reviews it is difficult to make an informed decision. I was so impressed (and surprised by the result) I thought the product deserved a pictorial review.
