The worst thing about kids (aside from being fragile and crying a lot) is that you have to teach them to do things. That is why I like gadgets that will teach them for me. The Tio Ghost light does just that and then some.

Using bright colors to illustrate how long household lights have been left on. The Tio Ghost Light glows green when the light has been left on for under an hour, yellow for a bit longer, and red is that color you don’t ever want to see. Perfect, you can let technology teach them!
