Microgravity in a small drop tower

Our daily "fight" against gravity begins already in the morning. Getting up out of bed demands an expenditure of effort which makes it possible for us to stand erect and walk. Without being aware of it, we are making use of a famous axiom of Isaac Newton, "action equals reaction". That means that for every force there is an equal and oppositely-directed reactive force. We all know from experience and observation how objects behave under the influence of gravity: objects fall to the ground; heavy liquids like water don't mix with light liquids like oil.
