Is there any easy recipes for non-dry silly putty?

Answer 1

The name brand "Silly Putty" acquired in the late 1970's by Binney & Smith, Inc. (which is now Crayola) in fact does not dry out, and is mostly packaged in the plastic eggs because an egg carton was used as a measuring device when it was first being marketed as a novelty toy item. I know that the store bought putty doesn't dry out because I've had a blob of it sitting out on my desk for several months now. Seldom does it get handled & very briefly when it does, is either by me or my guests who feel the urge to squeeze or stretch the strange substance. Here is a video demonstrating the complete manufacturing process; http://www.webcastgroup.com/client/start.asp?wid=0671023062859 it explains that it's made up of clay, solidified silicone oil, & Oleic acid. Although the exact measurements of the ingredients are not given in this video, you could get a rough idea of the substance proportions. However looking on the Wikipedia website http://en.wikipedia.org/wiki/Silly_Putty you'll find all of the ingredients & their percentages, and a detailed summary in the synthesis of silly putty and also cautions that there is a violent chemical reaction when mixing the given elements together. I too have looked for a similar homemade recipe, but never finding anything alike that of the original. So in short, unless you're a chemistry major; the answer is no - there isn't a relative recipe for a 'non drying' Silly Putty. For more info the video in the link above is nearly 30 minutes long and provides a very thorough explanation regarding the history of this non-Newtonian fluid.

Answer 2

All Silly Putty will dry out, that's why it's packaged in a storage egg. There are clays that don't dry out. Crayola puts out one.

Answer 3

Yes, all playdough and silly puddy dries out. To keep it from drying out, put it in the egg. It will dry out in a matter of 1 or 2 days.
