Experts say the ‘kit’ can be used to create a toxic gas or explode a device that kills people.
“This is a very dangerous and potentially life-threatening kit,” said Dan Toth, who studies explosives at the University of Maryland.
He said a small amount of the gas can be detonated by hand.
The gas can also be detonated remotely with a cellphone, which is easier to carry than a bomb.
Experts say that because of the way the kit is made, it could be carried by someone with no idea how it works.
“I would never recommend it, but it is a dangerous tool,” Toth said.
Experts also said that a kit containing the gas or device could be used as a weapon.
“You could put a device on your head, and then it could go off and kill people,” said Eric Kriegel, a forensic toxicologist at the Johns Hopkins University School of Medicine.
The ‘bathbomb’ kit, manufactured by a company called Fuse, is used by police to make improvised explosive devices, or IEDs, to blow up homes and businesses.
A typical kit contains chemicals that could be toxic to humans, but experts say they are not capable of creating a lethal dose.
“It’s not designed to be used by a criminal or someone who wants to use this as a suicide tool,” said Toth.
He added that Fuse has not tested the product for lethal toxicity and does not sell it to anyone outside of the United States.
But a spokesman for Fuse said the company has tested the kit on dogs and cats and that it does not have the capability to make a deadly poison.
Fuse spokesman Robert McDaniel said the kits were developed to provide a safe and effective solution to the destruction of property and buildings.
He also said the “kit” was not intended to cause harm to people or animals, but is only designed to kill or harm.
Experts believe the kit can be made cheaply in China and other developing countries, and that people who are not trained in explosives could use it.
Toth told CBS News he was skeptical about the effectiveness of the kits.
“They’ve got no real safety precautions, so I don’t think you’re going to make it safe,” he said.
But experts agree that the kit has the potential to be very deadly.
“There are a lot of people out there who don’t know what they’re doing, and they can end up putting their own life in danger,” said Kriegels assistant professor of forensic toxicology, John Wohlgemuth.
“These are the kinds of people who will try to do this.”
The National Rifle Association did not immediately respond to CBS News’ request for comment.
In February, the FBI reported that there were 4,000 cases of domestic terrorism and 1,500 other violent crimes in 2016. More:
