I just got a packet of Model Magic to make a tiny object, so I'll have a lot of excess MM left over. The packaging has a blurb on it: "It is not recommended to store Crayola Model Magic Modeling Compound for reuse." Does this mean once I open the package, any leftover MM will get wasted? If it is storable once opened, what would y'all recommend to keep in a state of near-freshness for a short period of time until I can figure out what else to make with it?
I've had some un-used model magic for over a year now. I've kept it in a ziplock bag and periodically put water in the bag with it to keep it moist. Since this is foam it soaks up the water after a while. Oh and squease as much air out of the bag as possible.
