How to fold a Water Balloon Yo-yo

Tuck the four corners back to make an octagon, draw the pattern and the knot, and add a string like a water-balloon yo-yo.

Steps

Step 1Start with the colored side up. Fold the bottom left corner to the top right corner and unfold, to make a diagonal crease.
Step 2Make a crease along the other diagonal too. The creases cross at the center of the paper.
Step 3Mountain-fold the top left corner behind. Fold it so the tip reaches a point on the crease a little closer to the center than halfway.
Step 4Mountain-fold the top right corner behind by the same amount.
Step 5Mountain-fold the bottom right corner behind the same way.
Step 6Mountain-fold the bottom left corner behind too. Now you have a round octagon.
Step 7Draw curved stripes from top to bottom. A small white spot looks like a shine on the balloon.
Step 8Draw a knot at the top and attach a rubber string with a loop for your finger. The yo-yo is finished.
