Silly putty recipe silicone8/9/2023 ![]() Best solution? No…but it made a really cool sand that is moldable, stretchy, and dry to the touch. Artist George Horner’s paintings are produced on an unusual canvas. So what did we do to make our kinetic sand work? We used an older batch of Liquid Starch Slime that was starting to deteriorate and very very slowly mixed in a pinch at a time. No word on whether the animals enjoyed playing with Silly Putty as much as their human counterparts. Add 1-2 tablespoons of dishwashing liquid to the bowl containing the cornstarch. ![]() The bowl doesn’t need to be very big as this recipe doesn’t make a whole lot of putty just enough for one child to play with 2. Dry pigments and clay carbonate are added to make color and glitter. For the Silly Putty recipe used here, please visit our web site at. Silly Putty is a mix of silicone polymers (about 70 wt), boric acid, and other chemicals. Silly Putty was discovered in 1943 by James Wright and introduced to the public in 1950 by. So I went on the hunt for a product that used hydroxy-terminated polydimethylsiloxane of low visocity…and yeah no luck finding anything in my area that even came close for a reasonable price… Start by pouring ¼ cup of cornstarch into a bowl. Silly Putty is a polymer made from silicone oil and boric acid. Silly Putty is made primarily from silicone and color pigments. The invention of Nutty Putty, later renamed Silly Putty, happened accidentally. Which technically should work…but, at least for me, this was a MAJOR fail (even with long bake times prior to mixing in attempts to dry out the sand completely). Wright (Ma August 20, 1961) 1 unreliable source was a Scottish-born inventor, researcher and chemical engineer at General Electric who invented Silly Putty in 1943 while looking for a replacement for rubber. Most of the DIY Kinetic Sand recipes I was able to find out in internet land used the PDMS dimethicone which is popular among cosmetics or products such as liquid starch. This is a known main ingredient in silly putty, but so is boric acid, so a part of me is wondering if boric acid is also included in the kinetic sand that is sold. The ingredients listed for Kinetic Sand claim 98% sand, 2% polydimethylsiloxane (aka silicone oil). While this sand had a lot of the same attributes, it missed some of the stringiness that kinetic sand has. The more water in the mix the less similar it will be. I have a couple more ideas on what to give a go…so we shall see how those go. This recipe was definitely a process of trial and error for me. ![]() This recipe for DIY Kinetic Sand is very similar to what is available for sale, but it is not quite exactly the same. And when it comes to sensory play materials we spend through them like no tomorrow so having an affordable solution is a must. My kiddos are absolutely in love with Kinetic Sand however, the stuff isn’t cheap. The goal of this experiment is to synthesize bouncing putty, a cross-linked silicone polymer, and study its unique properties. ![]()
