First make a hole on top of the can, then cut the can open.

Kui oled konservikaane sisse augu teinud, ava see ja söö sprotid ära.

After you have eaten the fish, take a piece of string.

Or if you don’t have some kind of string at hand, make it yourself.

Like from toilet paper.

Then put the string through the hole on top of the can.

Lambi tahi saad teha näiteks WC-paberist, kui sul parasjagu midagi paremat käepärast ei ole.

Pane see lihtsalt läbi kaanel oleva augu.
