Silly Putty prac

Today we created Silly Putty. Is it a solid or liquid? When mixing the ingredients together, why add more borax to thicken the product rather than PVA glue?

  1. Do you add more Borax instead of PVA glue so it keeps its shape better? I suspect it would be too sticky with more glue?
