I agree with the other review. Even when I put the pipe pieces together as tightly as I can the water pressure pulls the pieces apart. Very frustrating. And there are not enough pieces for two children and a parent to build together. There should be a supplemental set with extra pipes.

My 4 year old loves it! We bought one set a year ago and started as a tub toy. He built so many different types. He loved it so much that he didn't want to only play it in the tub and started building all day long. Here we are, an additional 3 sets later and he still absolutely loves them! I would definitely recommend this toy to any other little engineer out there.

Bought this for my 3 yr old grandson. He is fascinated in how water works in drains and where it goes. Gave it to him yesterday and his mom said he played with it in the bathtub all evening. His first words when he woke up this morning were that he wanted a bath. She had to do some serious coaxing to get him to come out and eat breakfast. Great toy! Highly recommend it and looking forward to getting more of your products for the kids.

Hours of fun,

My 3 year old is enjoying this enough but could you please include some sort of instructions to make this functional. I am not an engineer and when theres an excited child you just want to get the building over with!

This toy is engaging and Interesting for my child.

We use it in the bathtub. I constructed these suction cups on zip ties that allows me to easily place them where needed, and temporarily, but also very securely stick it to the tile wall. We make a new design every few nights and have the best time running marbles and water through each one over and over again.

I bought this for my two kids - 2 years and 4 years old- and although they could put the pipe pieces together, they did not stay connected for very long. Even when I put them together tightly myself, the pipes would come apart due to the pressure of the water poured inside. Also, there are only 52 pieces and not enough to create any stable water pipe structure that can stand erect by itself. I was really disappointed in this toy. It's definitely not worth the price and can be very frustrating for little kids and parents alike.

This learning tool is engaging as well as exciting because of the thought process it teaches. The fact that there are endless configurations also makes it worth the purchase price.

My three grandsons absolutely love playing with these. Their imaginations are stimulated as each one designs his own structure. They go way beyond water conduits.

works right in with our project based learning about water. Not so easy for small hand to assemble because all the pieces are not interchangeable. The water exploration kit added to this make for hours of sensory water fun.
