Noodle & PalsTM Leuchtwürfel 6er-Pack

My toddler actually asks to get in the tub now, and the cubes glow the whole time without me touching them. Six is plenty since a couple stay lit while the rest dry on the ledge.

Bath time went from a nightly fight to something my 2-year-old runs toward. The cubes light up the second they hit the water and stay glowing the whole time he's splashing around. Six of them means there's always a dry one waiting when one finally dims out.

My toddler actually asks to get in the tub now, mostly so she can line up all six cubes along the edge. They glow the second they hit the water and the light stays steady the whole bath, no flickering. Only wish the batteries lasted a bit longer, but she's had them going every night for weeks.
