New design of of motorboat with propellor to push it across the water. Title reads: "... here's the All-British Hydro-glider, first of air-screw-propelled Fleet of passenger and mail carrying craft for rivers and canals." Small boat - the 'Solent Hydroglider' - as mechanic starts engine. The boats engine turns a propellor in the back which pushes the boat through the air. Various shots of the boat speeding about on the water. Odd looking invention. Close shot through propellor on back of boat. More shots of man trying to start engine. The hydroglider slips past an old sailing vessel.

Presentation of weird and 'useful' inventions of the British Army. Military Engineering Establishment in Christchurch, Hampshire L/S of a line of vehicles crossing the river on a big float. Float reaching the shore, arriving at bank. M/S of two officers observing the operation. "Just once every four years this secret establishment (Military Engineering Experimental Establishment) opens its door to show us some of the weird and wonderful contraptions its back-room boys have contrived." There follows a succession of shots of these "weird and wonderful" inventions demonstrating their 'excellence'. Truck rolling out metal stripe from the back, around the front and under the wheels to make a 'road' - device against mud. However, the metal strip rolled around the front of the truck prevents the driver from seeing where he is going! C/U shots of the two strange looking tractor-like vehicles following the 'road making truck' and a yellow tractor getting out of the water. No demonstration of their use - they are for display only. Beach landing vehicle is a large and complicated looking amphibian construction which carries two boats (one at each side of the vehicle) and has something that resembles a bulldozer mouth in the middle - a beach landing bulldozer! Large balloon placed into the shell hole enables the tank to drive over it - simple! Trench making machine works on the principe of coal-cutting equipment. 'Instant trenching demonstration' looks amazing. Bulldozer (or any heavy equipment) can be dropped from the air thanks to the use of air cushions placed underneath the platform on which the bulldozer sits.
