This is really an easy, fun project for both kids and adults to make with a very cool result. They make the perfect gift for kids, or adults for that matter, and a perfect kids-friendly craft for any party with kids involved. All you need are some flour, a bag of colorful balloons, a couple of appropriately sized plastic bottles. Once finished, you will have a whole bunch of squishy, fun balls that are durable and perfect for juggling, or anything the kids can play.
To make this, first you need to cut the bottom off a plastic bottle and use it as a funnel (you can use funnel directly, too) to fill the second bottle with flour. Once full, place an air filled balloon over the mouth of the flour-filled bottle and flip it upside down. Shaking it, fill the balloon with flour. Get all the air out of the balloon, then cut off the top. Take another two balloons with the tops cut off and place them over the first, making sure to flip them each time so the holes are covered.
Now for the ninja masks. Cut a balloon as he shows you in the video, then put it around the outside of your flour ball. You can use any imaginable color combination to make unique and beautiful designs. They are very durable, hold their shape when squished, and are solid enough to make perfect juggling balls.
