Foutain in Vacuo

| View Cart ⇗ | Info

“Draw out a piece of glass tubing to a jet, and push it through a perforation in a cork that snugly fits a bottle. Slip a short piece of snugly fitting rubber tubing over the outer end of the glass tubing, and insert the cork so that the jet shall project into the bottle. Remove by suction as much air as possible, pinch the rubber tubing tightly, place it under water, and remove the pressure. Something will force the water into the bottle, forming the ‘fountain in vacuo’ as shown.” -Avery 1895
