Was thinking earlier how much things have changed in the stands compared to yesteryear. What don't you see on the terraces anymore that used to be commonplace? I'll start with a few.
Klaxon horns. These were popular in the 80s and the early 90s. I've not heard one at a match for a very long time, not that I want to, it's just strange how they just disappeared from matches completely, almost overnight.

Bog Rolls. Throwing one so that the whole thing unravelled mid air, while not snapping it was a skill which took many attempts to master. Many a bloke down at the front of the Tiv accidentally received a full bog roll to the back of the head during the learning process. I remember meeting ating up with my mates before a home game against Blackpool when we were about 14, all armed with our own toilet rolls which we'd brought from home! I have no idea why this was a thing? But its something we no longer see on the terraces .

Confetti. Or just a load of cut up paper, usually thrown into the air when the team came out or while celebrating a goal. The only reason I can think of why this was done is, it looked pretty cool from a distance. These days, ripping up a 50/50 raffle ticket or a match ticket just isn't the same spectacle as a pocket full of tiny paper cuttings. Now obsolete.

Blown up condoms. There was always a Johnny or two floating around the Tivoli end back in the day!
