THE SEA-HORSE’S SECRET
Anyone who has seen a sea-horse at tho zoo must have wondered how this quaint creature can rise vertically in its tank simply by the use of one tiny fin. The same problem Is receiving the attention of Air Ministry experts, who are trying to evolve a power-driven, weight-carrying apparatus that will rise straight up from, and descend in, any quite restricted space, and that will come to a standstill in mid-air without falling. It is also thought that the fin-shape of the sea-horse might help toward the design of the auxiliary surfaces of a vortical-flight air machine. The action of the humming bird is also being studied, and films have been taken of the movements of its wings when it is hovering in the air.
