Modern-day treasure hunters are making unusual finds.

Magnet fishing hobbyist James Kane, 39, uses special equipment to fish for sunken metal objects in park lakes around New York City. The neodymium magnets he uses can carry from 2,400 to 3,800 pounds of weight.

The Jamaica, Queens resident shows his finds on a YouTube channel that he and his wife run. During Kane's fishing expedition in Prospect Park Lake, he reeled in garbage, seven Citi Bikes and a safe with a crab inside.

They also made shocking finds like a rusty Hi-Standard Model 102 Supermatic Citation pistol, dating back to the 1960s and '70s, and a Smith and Wesson handgun.

"They weren't there because someone slipped and dropped them. I mean, they were there because they shot somebody and threw them in the water," Kane told the New York Post.

Kane had to call 911 to report the guns and police arrived to cordon off the area for a crime scene inspection.

Meanwhile, on a beach near Corpus Christi, Texas, researcher Jace Tunnell of the Harte Institute for Gulf of Mexico Studies has been collecting curious artifacts that had washed up onshore since 2017.

Tunnell uses her backyard to display the creepy bottles containing a variety of items, including hair, herbs, local plants, nails and even bodily fluids. Some of the bottles were manufactured in  Haiti.

When Tunnell pulled in the most recent bottle, filled with vegetation, on 15 November, she told Fox News Digital she was not going to open it.

That's basically the rule when stumbling on a "witch bottle," to leave it corked and its spirits contained, according to the Museum of London Archeology Department.

The McGill University Office of Science and Society explained that such bottles trap the evil spells of witches.

Tunnell said that witch bottles that contain malevolent spirits are popping up along the coast, so beachcombers who spot them should exercise caution.
