Audio Guide:
How does a rocket create thrust in space where air does not exist? It relies on action and reaction forces. When a rocket expels gases in a high speed, the reaction force creates thrust for it to move forward.
Visitors can experience action and reaction forces through mechanical devices, such as sailboats and launching rockets. 

Exhibit Introduction:
Mechanical models are adopted to display action and reaction to illustrate the principle of rockets advancing. Meanwhile, phenomena of action and reaction in our daily lives will be shown on the screen.
