ELI5: Why are fizzy canned drinks in thin cans, while non fizzy canned drinks in thick cans? Wouldn't fizzy canned drinks need to be in thick cans to prevent then from exploding?

The carbon dioxide is able to keep the cans solid enough for transport, as it is able to press against the walls.

Uncarbonated drinks however, do not have this pressure, and with thin walls would be very squishy and crushable (Cans would get squished and possibly burst or something). To counter this, they need thicker walls.
