With the official start of spring less than a month away, it's a good idea to have a working flashlight handy.
The makers of the Hydralight say it's a flashlight that runs on water. It's powered by a water-activated fuel cell and claims it only takes a little bit of water to work.
The Hydralight flashlight slash lantern is supposed to be able to run up to 100 continuous hours.
Does it work as advertised?
To find out, Eyewitness News got some help from Jordan Benton, a space science educator at the Kansas Cosmosphere to put the Hydralight to the test.
