How cool is slime. We love slime!
As a kid, Ghostbusters was huge. We had it all over our arms and did the whole "He slimed me".
Fake snotty sneazes were a thing. We'd sneaze blocks of snot on to our hands and gross each other out.
Parents thought it was disgusting too, which further added to it appeal.
The kids who had slime to play with were the coolest. That was how it was back then, and still how it is today.
