Polish pupils have made paper boats which have managed to flow with the help of the wind and water currents. Here you can see the links to short films documenting our work:

Ecological, moveable machine constructed by class IV c
It`s half a car- half a yacht. The base of the vehicle
is a piece of foamed polystyrene wrapped around by old fabrics , a sail is made
of linen and wooden barbecue sticks. The most difficult part of our project was
the way the machine should be moved- how to connect the driving axle (wooden
sticks ) with wheels (plastic caps from bottles) to the main part of the
vehicle ?!
But finally our inventor FILIP solved the problem – he
used old metal clothes clips and some plasticine !
We tried to give the movement to the vehicle by
blowing into the sail. At first we
practiced with the power of our lungs
(the results weren`t satisfied ) then we used the stream of air produced by
hairdryer. Although our vehicle moved not too far the young inventors were
happy!!!
