Making a Wash Bottle or Gas Bubbler
A two-hole stopper turns a flask into simple apparatus. For a glass wash bottle, you blow into a short tube in one hole, and a long tube in the other, reaching the bottom, sends out a jet of water. Feed gas in through the long tube instead and it bubbles through the liquid and leaves by the short one, as when carbon dioxide is passed through lime water.
