I got another question,
Theres a bridge made of wood which is very old(and a very long one) , in some places in the bride some planks are missing. below the bridge is a river , and in the river is a boat which is right under the bridge .At the same moment a hen goes walks on to the bridge hoping to cross to the other side, suddenly it wants to lay & egg :O !!
it lays the egg , Where does it fall ??
