A product that will still work after sitting for up to 10 years, according to reports. And to turn it on, you just have to add water to it.

For the initial startup, you have to dip it in a small amount of water. Or just pour water into the battery compartment. After that it will continuously work for 72 hours and may the light start to dim, you’ll just have to add some more water.
