Sir, – I have been picking up plastic bottles and cans by the roadside. “Energy drink” containers are prevalent. It appears that some people are getting so much energy that they are capable of throwing the bottle or can out of the car window, but not quite enough energy to bring them to the recycling banks. Can anybody explain this energy fizzics? – Yours, etc,
