“Sun’s out, solar balloon’s out” doesn’t rhyme, but that doesn’t make it untrue. The heat from the sun and differences in air density, the exact science that keeps hot air balloons afloat, raises the giant balloon into the air and keeps it there until you’re ready to bring it back down. (There’s a release flap; you won’t need to wait until nighttime.) Put away your air pump and let the sun save your lungs some work—this 50-foot balloon launches using nothing but solar power.
Recommended for ages 14+.
