We provide to the group different materials: wooden sticks of diverse sizes, adhesive tape, rope, multipurpose knife, an elastic rubber, etc... They will must design and build a catapult that should be able to throw an egg. The dessing will be always well considered but, the most important thing will be the number of meters that the egg will be able to fly.

Once built all the catapults, we will position them before a field of defined launching lines each 5 meters.

We will encourage the members of each team to be located at the launching field. We will provide appropiate protection dressing and the target will be to catch the egg before its arrive the floor. The hunted egg will punctuate double.
