I mentioned Silly Soap the other day.
I'm sure I recall something like that. Here it is as featured online. Soap in a spray can.
I could be wrong. This could just be my mind playing tricks on me.
For example, there were other silly products like silly string, which you can still get.
And then there's Crazy Foam!
My memories a bit like crazy foam drying up. I just can't decide if I really did have any of these as a kid in the UK in the Sixties.
