Sky Lanterns are an amazing addition to any celebration. Sky Lanterns are basically small, translucent hot-air balloons. They have a small fuel source in the middle that, once lit, will lift the lantern slowly into the sky with a soft glow. These lanterns are made with fire-retardant, 100% biodegradable material. To achieve the best effect, at least 10-20 should be used at one time (the more, the better).
