Video camera
Everyone knows that photographs cannot fully capture the surrounding reality. After all, all they do is freeze a single transient moment. All the shortcomings are perfectly supplemented by videos. Thanks to this invention, you can once again experience what you felt during the expedition, remind yourself of the good times spent among friends.

Remember about spare batteries and storage media. Make sure what voltage and what type of electric sockets are used in the country of your destination. It may be necessary to take adaptors or even a converter, if the voltage is 110V (such equipment can be purchased in electrical stores or at airports).
