Of the usual litter I collected today, the oddest was a heavy (2-3kgs) cylinder called Fastgas. I Googled it thinking it must be a car accessory that a motorist casually threw on the grassy kerb after pimping up their car. Apparently this Nitrous Oxide cylinder is used for...whipped cream!

There goes my theory (and silent judgement) of obnoxious vehicle customisations!

Why would someone dispose of a whipped cream maker on the roadside (there was no house nearby either). Did someone have an impromptu dessert-car-picnic? Or did they use it as a weapon and discard the evidence (not clever)? 

If you can think of something, let me know in the comment!
