How do you open vintage seltzer bottle?

To open a vintage seltzer bottle, first ensure the bottle is upright and the nozzle is directed away from you and others. Carefully remove the cap by unscrewing it counterclockwise, taking care to avoid sudden pressure release. If the bottle has a metal cap, you might need a bottle opener to pry it off. Always handle vintage bottles with caution, as they can be fragile and may have residual pressure.
