Boon Tubes - Azul Multicolor

The suction cups hold surprisingly well on our tile wall, so my kid can stick and re-stick the tubes without frustration. Water actually flows through the whole setup, which kept him entertained for a solid 20 minutes tonight.

My toddler is obsessed with connecting the different tubes to see the water flow through them, and the three pieces are just the right amount for a quick bath. They stay put on the tile and are easy for little hands to snap together.

The suction cups hold well on the tub wall, but my toddler lost interest after a few minutes since the tubes just sit there without water flowing through them unless you aim the faucet just right. They're sturdy enough, though, and easy to clean.
