Here comes some giant-sized solar science fun! This 50 foot long balloon soars high in the sky powered by the sun. The Solar Ballon demonstrates buoyancy, convection, thermodynamics, and solar power, and teaches Bernoulli's Principle and Pascal's Principle. It's great for science classes and the perfect start to a science project. Bright direct sunlight on a calm, cool day has the Solar Balloon soaring in just minutes.
