I have in my basement, the toy from Mattel called "vacu-forms'. It was a machine with a handle that, when turned on, created a flow of hot air. You put a plastic square over a hard plastic mold ( it came with little molds like toy cars), pumped the handle and it'd suck the plastic sheet down over the mold and Ta-dah! you had a toy. It's still in its original box, has most of the forms, thenow- dried up paint bottles and probably a few sheets of plastic. The box says copyright 1964-I think we bought this a couple years after that.
I have a Chatty Cathy that still talks(but I got her a few years ago from an estate sale)
Remember the bar of floodlights your dad had to hold up while filming with his Super8 movie camera?
