UFO Unidentified Floating Object
Each team receives the necessary material in order to build their own U.F.O. Some participants are better in imagining the hull, some in constructing, while others will be responsible for the painting and decorating : each person adds his personal touch !
Once the construction time is finished, the rafts will be judged on their aesthetic aspect. Finally a race will determine the most performing U.F.O. and the winning team will be rewarded.
This activity can also be organized indoor, in this case we talk about U.R.O : Unidentified Rolling Object.
