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.

This stuff is AMAZING! I originally purchased it to make a replacement tooth for mom's dentures. She was delighted. Even after "staining" it with tea it was whiter than her teeth but that didn't take away from her joy. She loved having a tooth where there wasn't one before. =) It is really easy to use, versatile and reusable. Although I noticed that the times I did reuse (by putting the piece back in hot water) it was no longer as pliable as the first time. So try to get it right the first time if you can. It's so useful that you will keep it in mind as you notice things needing repairs throughout the home. I have used it so far on these things (in addition to the tooth):-Closet hanging rod was too short and kept falling out of the holder. I added length with this and it has not fallen since. Almost 2 years!-car key fob lost the plastic housing on one side, exposing the interior "guts." I covered it with this and it worked like a charm.-shower head knob to select setting broke. I created a new one with this. I can now change the settings. Barely used a quarter teaspoon of pellets!I know I've used it on some other things but can't remember off the top of my head. I've had this over 2 years now and still have about a third of the product left. A little goes a long way. Truly happy with this!
