#8 "Why is there Pepsi all over my lap?"

This "Scream machine" with the words HAVE A PEPSI DAY, whatever that means, was a cup that had a bottom that could be punched out to create a loudspeaker type effect, presumably popular at sporting matches.
......Very rare collectors items with some colours fetched over $500 each. yes for a single plastic cup!
......Came in Yellow, White, Orange, Green and Blue.
