solar airship
A physical experiment with solar energy. One of our most interesting articles, it is fascinating due to its great size 3 x 1 m and clearly illustrates the effect of the warmth of the sun. The tube is filled with some air, both ends are tied closed and then in a short time the solar airship will begin to rise. This is due to the expansion of the air in the tube resulting from the absorption of the sun's rays by the black body of the tube. Contents: black plastic tube 3x1 m, 50 m nylon thread to tie and instructions.
From 6 years - with an adult - a physical teaching and learning object on the topic of solar energy.
