Glo Pals Water-Activated Light-Up Cubes for Sensory Play – 12 Pack

These are so awesome! They light up immediately after touching water, the glow is strong, and the little faces are adorable. I rinse them and shake them after use to extend the battery life. My toddler is obsessed already! My only concern is longevity. Of course I dumped all 12 into the bathtub bc what fun is it to not have a tub full, however the instructions say they last for “more than 30 days.” I can’t say as to how long they will last because we have only had them for 2 days but $35 for a month is too pricey for me to buy again (if that is the case).

Make bathtime fun with this set. The kids love it and it's a great distraction, which helps if you feel like you're fighting an aligator every night.

My kids love these! They last a long time, very bright, I wish the batteries could be changed though

Very cool bathtub fun

I love the idea of these things and some of them work great but after about a month of almost daily use in the bath several have stopped working and other are still lighting up very dimly.
