Is there a way to get old toy magic bottles/cups working again? The ones where it looks like the "milk" is gone when you tip it.
We have 2 and neither works now. I've tried hot water and now trying cold (freezer). It seems like the stuff has dried up and/or turned transparent. Don't think it's leaked out. Thanks!
(They are cheap but I don't want to buy more, just wondered if I can revive them somehow).
