Have you ever had something pop into your head that you have not thought about for literally 50 years? That just happened to me. Can't explain why it popped into my head but now it's driving me crazy. I remember a "toy" that I once played with when I was probably about 10 years old or so (that would be about 1967 or so). It was some kind of a thick chemical paste in a tube with a screw on cap. I would squeeze some of it out and put it on one end of a straw that came with the toy. I would blow into the straw which would create a strange textured bubble that I would then twist to seal off the bubble before pulling the chemical bubble off of the end of the straw. You could then hold the bubble in your hand and play with it as it hardened. It never got totally hard but it was pretty difficult to pop. Does ANYONE remember what that toy was called?
