Checkered Round Sphere Foil Balloon

Insert a handheld balloon pump gently into the balloon’s neck. Avoid using a straw or sharp objects.

Begin inflating slowly. As you pump, the balloon will start to unfurl and shift shape — don’t worry if it doesn’t look round yet!

Continue inflating. The balloon will first appear wrinkled and squarish. This is normal. Keep going until all seams are smooth and flat — that’s how you know it’s fully shaped.

Once the seams are completely smooth, stop inflating immediately. Remove the pump. The balloon is self sealing so no tying necessary.
