Heat some water to approximate 150 degrees F. Water can easily be heated on a stove top or in a microwave oven.
(You can also also heat InstaMorph using hot air from a heat gun or oven. The InstaMorph pellets must reach the same activation temperature. Once achieved, you can skip to step 5).




Pour InstaMorph pellets into the water. Don’t worry if it isn’t enough to finish your project, you can always add more InstaMorph later.




Wait approximately two minutes or until white InstaMorph pellets turn clear and stick together. This is when you’ll know they are ready to mold. If they haven’t turned clear, try increasing the heat just a little bit.




Remove from the water and get rid of any remaining liquid between the pellets. Be sure to use tongs or some other type of tool (not your hands) as your InstaMorph will still be quite hot.




Once removed from water, InstaMorph will be cool enough to mold by hand. Form into desired shape with your hands, tools, molds, or any other means necessary.




Once you’ve got your InstaMorph creation finalized, let it cool to room temperature. You can place InstaMorph in ice water to speed up the setting process. Once completely cooled, InstaMorph will then be as solid and strong as before it was heated.




Besides hot water, InstaMorph can be warmed to it’s activation temperature of 150 deg F using other heat sources. For example, you can use:

  • Oven – place InstaMorph beads on a non-stick surface until they turn clear.
  • Hot Air Gun – These are available at your local hardware store and are more powerful than your normal hair dryer (those work too). If you use this tool, be extra careful, as a hot air gun’s working temperature can be upwards of 1,000 deg F. You increase the risk destroying your InstaMorph and/or causing nasty burns to yourself.

Heating Above 150 Degrees

We frequently get the question of how to make InstaMorph stay moldable for longer. One simple method is to heat up the InstaMorph a bit higher than the recommended activation temperature. With the higher temperature, the plastic will stay above the temperature needed to stay moldable for an increased period of time. This does increase the overall temperature of the material though, which increases the risk of a heat related injury (see warnings below).


We’d like to think that if you’re smart enough to realize the amazing possibilities of moldable plastic, we wouldn’t have to tell you this, but we’ll do it anyways…

  • Burns suck. Be careful when heating water or using your stove or heat gun to heat up InstaMorph. Heating InstaMorph above 150 degrees F increases the likelihood of heat related injuries.
  • Small pellets of InstaMorph could be a choking hazard. Please supervise small children when using InstaMorph.
  • InstaMorph can stick to different materials when it’s hot. Sometimes you want this, sometimes you don’t. It can stick to the following including but not limited to: metal, other plastic, vinyls, fabrics, acrylics (like fake fingernails or plexiglass), and styrofoam.
  • Because of the unique remoldable property of InstaMorph, you should keep your finished pieces away from sources of extreme heat. We would hate to see you lose your amazing creation in a tragic space-heater accident.
  • Although its non-toxic, InstaMorph has not yet been certified “safe for internal use” or “food contact safe”.
