Home advantage is something which affects many sports, and no-one knows quite why. Huge amounts of money are spent by professional teams in filming the changing rooms they will visit in a season, for example.
Today’s invention is a way to employ this phenomenon in a new way.
Knowing the power which smell has to evoke feelings, each club would trademark its own local odour. This would be sold at grounds in aerosol cans, adding another source of revenue.
When travelling to away games, these cans would allow each side’s supporters to express their allegiance and also to provide their team with memories of home wins at critical points in a match.
