Was making it with kids today and talking about the gluten, the oil, the water and then ds1 asked what the salt was for.Discuss
I think it heps to preserve the playdough. Also, it deters children from eating it, yuck!
oh i used to quite like it. yes preservative.
OK, but HOW does it function as a preservative? Is it a baceteria inhibiter? is it a dessicant? Is it so kids don't eat it?
I think it provides a hostile environment for the bacteria. (Like with bacon)
thank you smug colditz
The salt draws out the moisture too & bacteria need moisture to grow - hence no bacteria
Makes it taste horrible too
