Styrofoam sailboat craft

Now that the summer is here, my 3-year-old plays with water a lot. naturally, she wanted a sailboat to play with, so I had to think of a very easy way to make one with minimal supplies.
In case you 'd want to make one (or more) as well, here are the instructions for the most basic yet efficient styrofoam tray boat.
Foam tray and bamboo skewers are all you will need. Enjoy!
