How do I open the soda bottles?

You'll have to set them on a flat surface somewhere first.

You'd think you there would be a single bottle opener on this island somewhere, but unfortunately that's not the case.

There are alternative ways to open bottles, thankfully.

You can use something you already have in your possession.

Not your teeth, no.

It's a tool that has come in handy before (and will again). Yet it's not really a tool at all.

It has holes.

Use the eight on the bottles.
