The Vinelings' Secret Method of Making Hydrogen Balloons

The British army were experimenting with hydrogen balloons in the 1880s. Hydrogen molecules are so tiny they escape from almost any bag that you keep them in. The Vineling family had their own effectively secret proprietary method of making these balloons. They'd made some for a scientific toy shop in the east end of London, which is called Mr Herons. Henry Coxwell who was walking through this scientific toy shop and saw this thing. He hired the Vineling family to teach him how to make ballooning. It's pretty amazing as well that it's, it was a guy called Henry Coxwell Who discovered Gold Beetle Skin.
