Was plugging a thumb tonight and had my stir stick sitting on the bench in the mixing cup. I noticed a Nick in the coverstocks of the ball, so put a thin line of control gel super glue in it to fill it in. To smooth the super glue out a bit and make sure the Nick was filled, I grabbed the stir stick (stillnhad a bit of wet plug on it) and rubbed over the top of the glue.
Holy chemistry! Instantly there was a little grey smoke coming from the glue/ball! Given that super glue is iso-cyanonate, and therefore the potential for cyanide, I decided it best to leave the room!
Anyone see this before? If not, I don't recommend trying!
