4 toys you can make from balloons Modern Mechanix 1931.
These drawings show the construction of four novel toys made from circus balloons that will prove highly fascinating. Fill the balloon with hydrogen and attach to it a postcard bearing your name, and a request to return it from whatever point it falls to earth. Thus you can learn in what direction and how far it travels. Another balloon, equipped with a gondola will float in the air like a wartime captive dirigible. The aerial torpedo which zips up through the air is made by affixing fins to an air-filled balloon. The unique air boat cuts through the water under power of air exhaust from blown up balloon.
