Recently visited a beach in Greece it had changing room and showers with ice cold water. I was thinking such cold water going to waste, so i made a fridge. I had chocolates melted down i had to lick it off the packaging but not after 10 minutes in the fridge.
Dig a hole deep enough to cover almost the whole length of the bottle and wide enough to fit the number of bottles, make it wider if you wanna put chocolates in it.
Just keep it in shadow and add water around the pit to wet the sand ( it helps if its shower water cos usually its colder sea water is okif its really cold add some inside the storage bag).
