just spun off on my bike to the the off licence for some essential supplies. when i got home my beer was cooler than when i set off. obviously the evening air rushing passed the cans cooled them down.
but surely air moving round stuff causes friction and friction causes heat. (i'm thinking space shuttles here). so can anyone ease my saturday night by telling me how fast i can go before the friction from the air heats my cans?
i'm in on my own if you hadn't noticed.
