Simple, fun, and hands-on play. Today I created these simple boats for floating. For this all you need- -Plastic cup (cut the top portion of the cup off) -Straws -Tape or decorative washi tape It's so easy to put together, and my daughter absolutely loved watching them float. We took a bin and filled it with water. I added one drop of blue food coloring, and there you go sail away and visit a few sea creatures. We had a blast! Enjoy~
