This is the 'sponge bomb' with which Israel wants to disable the Hamas tunnels in Gaza

Israel's siege on Hamas terrorists is closing. The ground intervention of the Hebrew troops is imminent in Gaza, where the objective is to neutralize the network of underground tunnels that the Islamists have under the Strip.

To do this, Israel plans to use an innovative device called a 'sponge bomb'. These weapons are based on a liquid emulsion, a chemical compound that is dropped into a tunnel and then rapidly expands and hardens, trapping terrorists and ensuring safe routes for Israeli commandos as they search for hostages.

As reported by the Daily Mail, the Israel Defense Forces (IDF) have already tested these portable devices in a replica of Gaza, a model of the urban network of tunnels where they are soon expected to fight, and which has been built in the Urban Warfare Training Center in the Negev Desert.

These pumps have a metal partition that separates the two volatile liquids, which react immediately when they come into contact.. The material is highly dangerous, says this media.

The United States has already used weapons that shoot sticky foam as a non-lethal way to incapacitate enemies when American troops were deployed in Somalia in the mid-1990s, although the results were ambiguous.

Hamas tunnels under Gaza are estimated to measure hundreds of kilometers. Recently, Yocheved Lifshitz, an 85-year-old hostage recently freed by terrorists, said: “It looked like a spider's web, many, many tunnels,” adding: “We walked kilometers underground.”
