Balloon Powered Benchy Boat

This is a cool model that glides on a smooth surface when you fill the balloon up. Soon, I will have a version that is powered by 2 balloonsThe way to fill up the balloon:Attach the balloonBlow into the hole on the bottomWhen getting your breath back, pinch the balloon so it holds the air inRepeat steps 2 and 3 until you think the balloon is big enough
