Rain Water Alarm System projectRain Water Alarm System is a practical electronic safety and monitoring project designed to detect the presence or rise of rainwater and provide timely alerts.

Great for small kids
Format: Board book
Love this book. Easy for the kids to turn the cardboard pages, and the sound buttons are easy to push. Bought for my 2 year old grandson’s birthday, but 3 year old cousin keeps trying to steal it.

Cars!!
Format: Board book
Cats craze over at this household! My kid is obsessed and honestly so am I. We got this book as a Christmas present because we love books and cars. It’s loud enough and it’s fun to follow along and press the buttons . We take it on road trips and read it at bedtime. Definitely a great addition to our library!
