Kids think these are A-mazing!
My kids, (3 and 6) were captivated by these bath toys!  They light up in the water and run through several colors of lights.  They light up when the sensors touch water and when they dry, the lights automatically turn off.  I'm not sure how long the batteries will last, but this is a pack of 12 so it should last us a while!  My kids had fun putting them in the water, pulling them out to air dry for a few seconds so the lights would turn off, and then dunking them again.  They are especially fun with bubble bath because the bubbles will "glow" a bit if one of these toys is in the water.
