Magnet fishing is like fishing, but instead of a fishing rod and bait, you have a really strong magnet on a rope. You throw it into water bodies (like lakes, rivers, or ponds) and drag it along the bottom. The magnet is attracted to metal, so when it touches something metal, it sticks to it like a glue.
People do magnet fishing to find things that other people have lost in the water, like coins, jewelry, tools, or even old relics. You can find all sorts of things, and it's like a treasure hunt.
But, magnet fishing could also be dangerous if you don't know what you're doing. For example, if you pull up something sharp, you could get hurt. Also, there could be underwater cables and pipes that you shouldn't pull up with a magnet as they may cause damage or injury.
Overall, magnet fishing is a fun and exciting activity, but it requires safety precautions, like wearing gloves and being mindful of what you pull up.
