The recent heat wave is literally melting money in Canada:
“Confronted with photos of melted $100 bills, the Bank of Canada staunchly defended its new series of plastic currency as "the most durable bank notes ever issued" in the country.”
“The statement followed remarks by a credit union teller in Kelowna, B.C., who told a local radio station Tuesday she had seen melted polymer bills stuck together during a heat wave.”
