Wheres Toto Posted November 1, 2015 Share Posted November 1, 2015 Has anyone made Squishy Circuits? I'm trying to find out if it retains its conductivity if it dries out. I'm hoping to use it for project with my STEM 4-H. Thank you. Quote Link to comment Share on other sites More sharing options...
rmtzc2009 Posted November 2, 2015 Share Posted November 2, 2015 My son took a squishy circuit class. The dough molded before it had the chance to dry out. I think the dough lasted 2-3 weeks. Quote Link to comment Share on other sites More sharing options...
Wheres Toto Posted November 3, 2015 Author Share Posted November 3, 2015 I know it will last a few weeks if it's kept in a bag but I was wondering about making a project where it was allowed to dry out. Would it still work? I want to let my group make robots with light up eyes, etc. and was thinking about using Squishy Circuits because one of our projects with circuits they had a really hard time getting the wires to stay attached to the batteries and lights. I thought they would be easier but I want them to be able to take their projects home and continue to use them. I posted on the Facebook page for Squishy Circuits but it's not very active and I haven't been able to get an answer. This is the largest group of people I know so I figured I'd ask here. :) Quote Link to comment Share on other sites More sharing options...
fdrinca Posted November 3, 2015 Share Posted November 3, 2015 We had problems with our insulating dough (the formulation made with sugar) molding very quickly. I don't know if it would conduct if dry. I think it would corrode the metal components before it would completely dry, which would impede conductivity. Our squishy circuits never lasted more than a few hours anyway - they wanted to build and rebuild. Perhaps you can send it home with a recipe for the dough to use after the first batch starts to dry up? Quote Link to comment Share on other sites More sharing options...
