When a toilet flapper can help you remove stains from a toilet

A toilet flaperon can help remove stains in toilet stalls and even make a clean toilet more attractive to children, according to the US Department of Defense.

The US Defense Advanced Research Projects Agency (DARPA) has developed a prototype of a valve that can be used to release water from a flapper, a device that sits on the top of a toilet bowl.

It works by allowing the water to flow through a valve, which opens up a seal.

The device was tested in a water-filled toilet at a research facility in Virginia, the Associated Press news agency reported.

The team said they hope to eventually make a commercial version of the valve, according a DARPA news release.

But the team has not yet submitted its final designs, which could take several years, it said.

The flapper system was developed by US Army Corps of Engineers engineers working on a prototype that could use a hose to remove a stain from a water tank.

The idea has not been proven in the field, DARPA said.
