Valojuova from Finland has created a crazy DIY invention for cooling a can. The Peltier CAN cooler uses the peltier effect for cooling. Looking to cool a bit more with a peltier device? Check this out.
“PWM controlled peltier cooler, 12V, 80W peltier. I can holder was lathed from aluminium by some other students. I just gave him the blueprints. Hot side is cooled with Igloo 7200 Light. I haven’t really have time to test it properly but maybe I tell more when I’m done with report to my teacher.”

Popoular Science did a project almost exactly like this, only without the custom holder and a smaller heatsink.
