About This Product
The Solar Bag shows how heating air changes its density. As the sun warms the air in the black tube, the air expands and becomes less dense than the cooler air around it, and the tube begins to float. This is the same idea that explains why warm air rises and how hot air balloons lift. Pupils can predict what will happen, time how long the tube takes to rise, and discuss expansion, density and the sun as a source of heat. School Lab Equipment India can export the Solar Bag to education buyers in Mali, Venezuela, Japan, Ghana and Chile.
