It's almost identical to something like polypropylene in all its properties, so think of screw-on bottle caps or lunch boxes with flexible hinges.

In fact, if you have the right mold it is possible to create prototypes that look, feel and function like these items. It's great stuff! (btw, sold as polymorph in the UK)

Dig it! Thanks!

Just ordered some but have to wait 2 days for it...perhaps Quirky could bottle patience and sell THAT! LOL! Oh well, it's always cool to know a box of FUN is headed my way!!

Instamorph weights about 0.8 oz. per cubic inch.

In addition to its other wonderful qualities, it machines VERY well.

Thank you PILATVS - I have watched some videos of the melting process. It appears that one could simply insert any screw one might wished to use and allow the thread to harden around them, Is this correct?

@cindy - absolutely - I've actually replicated metal nuts and bolts in Instamorph. You can mold around a tripod camera mount screw and make custom flanges to mount almost anything on a tripod. Make custom handles for stuff and a million other practical and creative things.

Instamorph is just plain awesome and remember you can re-heat and RE-USE it again and again. Since it softens at only 140 degrees F if you remove it from the water with tongs you can almost immediately work it with bare hands if you want to. You can also "spot weld" it by dipping part of a model in the hot water while keeping the rest cool and solid (or use a heat gun).

Did you get yours on Amazon.com? I've got Amazon Prime so I gravitate to Amazon.

I used Amazon Prime too - supplies are usually much cheaper, there, with the free shipping! And they have everything from toilets to industrial supplies!
