Tapping into kids’s innate curiosity, Sink or Float allows players to guess whether various objects will sink or float when dropped into water. Including over 120 objects, this app allows kids to explore object density in a mess-free environment. Sink or Float has two play modes: play the game and drop stuff. The “play game” mode includes scorekeeping and rewards. In the “drop stuff” mode, kids can drop multiple objects, drain and refill the water tank, and play at their own speed without a score. Sink and Float can be used in the classroom as an extension of a variety of science lessons or as a take-home assignment to encourage parental engagement.

What Users Love About the App

“Pretty clever! Shows items that sink or float, then you get to tell which an object is, sink or float. When you get three correct, you can pop a balloon!”

“Good fun tossing stuff in water. Can’t get my phone away from my daughter!”

What Users Dislike About the App

“Only a few items available with the free version, once you learn those, no more game. Music setting keeps reinitializing with each return to home page. Deleted game after 5 minutes”
