I was on another forum talking about who was around the longest as a fan and someone brought up toys they played with as a kid and it got me to thinking. What toys did you have as a kid that couldn't be put out today in a million years. For me, there are a couple. The first is something called Creepy Crawlies:
Basically, you put this goop into a metal mold then put into a metal hot plate then cooked until hardened. This would never fly today. Would be deemed too dangerous.
The other is the good old fashioned chemistry set. Sure they try to pass off things called chemistry sets but I bet none of the ones today have Bunsen burners.
