When the purchase is complete, return to the original window. It will refresh.
From the opening
Ice melts faster in a crowd of warm cans because those cans are a store of heat sitting inside the cooler. Heat flows from the warmer metal and drink into the ice, and that heat is spent by melting ice. The opening covers warm mass is stored heat, contact speeds the transfer, and the rush ends once cans cool.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
