Christmas crackers spill plastic trinkets onto your Christmas table every year. Nobody keeps them; who even remembers what fell out of their Christmas cracker last year?
It all ends up in landfill with the paper hats. The hats will biodegrade in a matter of weeks but nobody knows how long the cheap petrochemical-derived plastic dinosaurs and whistles will remain in the ground. The best estimates of the time it will take such plastics to biodegrade are anywhere between 5,000 years and never.
