These Inflatable Plugs Will Block Out Floods, Smoke and More

Got a leak? Put a plug in it. That's what officials are going to install to halt the rising tides and floods with a device called a "tunnel plug".
The strong inflatable tube deploys from a folded up wall panel to fill every nook and cranny of a tunnel where it's installed. It will block out flood waters, smoke from fires, gas attacks and more.
The plug was designed by a Delaware company called ILC Dover, and they use the same super tough material used to make space suits. Originally developed as part of a project for Homeland Security, the plugs are designed to withstand 17 pounds per square inch of force using a super-strong pressurized plug with an internal capacity of 35,000 gallons, according to a PhysOrg report.
