Please can anyone out there help. when I was younger I used to have this toy that had water in the bottom and when you held the bottom in your hand the liquid would boil and move to the top. does anyone out there know what it might be called and where the hell I could get one from!!!
I think I know what you mean. The liquid would react to heat, then cool down, then start again. The version I had was a sort of nodding bird. Don't know that they are made now - my personal quest is for a mood ring from the late 70's.
