Air-filled balloons on frames are best for outdoor events. Because these Lollipop topiary balloons are air-filled, the heat does not expand the balloons as helium would. The satin-wrapped pole keeps the decor rigid, so it's not flip-flopping and hitting the grass. Only the ribbons sway in the breeze. We add 24 smaller balloons between the larger balloons in our deluxe version. We can make them up to 10 feet tall. Also, it is best to choose lighter colors. These must are installed in grass or dirt. We can add lightweight bases if the ground is perfectly flat, as these are top-heavy for an additional charge.
