A picnic, playdate or party at our house usually results in several empty juice boxes. We've already showed you a great way to reuse your glass baby food jars. How about scheduling your own regatta in a nearby creek with juice box boats?
Juice boxes float so they work beautifully for this project. All you need are some empty juice boxes, tape, Tyvek envelop (for the sail) and wooden skewers. Inchmark blog has more detailed instructions. She also suggests cutting a slit into the box and inserting some pennies if your boat tends to tip. Happy sailing!
