If I dig the land, do I get money? 'If you dig in the water with a magnet', you get money!

Let's go to America this time.

A man enters the pond.

I don't mean to swim.

This is so-called 'magnet fishing', in which a powerful magnet sweeps through the water of the pond.

If you dip it, salty~ It really comes out with all sorts of stars.

Coins are the most common.

These days, shared bikes and kickboards are coming out a lot.

If you sell and sell what you get, you can earn a savory side income, so it's called one stone and two birds.

Besides, since the environment is clean, I don't think it's a 'good hobby'.
