Solar Balloon

$ 19.99

  • Product Description

      “Sun’s out, solar balloon’s out” doesn’t rhyme, but that doesn’t make it untrue. Put away your air pump and let the sun save your lungs some work—this 50-foot balloon launches using nothing but solar power. Heat from the sun and differences in air density, the same science that keeps hot air balloons afloat, raise the giant balloon into the air and keep it there until you’re ready to bring it back down. (There’s a release flap; you won’t need to wait until nighttime.)
