Customer Reviews (4.3 / 5 · 3 reviews)

Henry B. ★★★★★

My son loves testing which balls float and which sink with the submarine—it keeps him engaged for way longer than I expected. The raft and weights add a nice challenge for figuring out balance too.

Lily ★★★★★

My kindergartener grabbed the two-piece submarine and started testing which items sink or float before I even finished opening the box. The raft and weights are sturdy enough for little hands to keep experimenting over and over.

David ★★★☆☆

The submarine and raft are fine for basic sink/float play, but the included balls and weights feel a bit flimsy for the price. It kept my kid occupied for a little while, though I wish the items were more durable.
