Collecting Hydrogen and Oxygen

Step 2 The Non-Electric Setup

Fill your bowl most of the way with water, the purity of which doesn't make much difference so long as you don't use mud or something. Now add your salt or weak acid to the water, it doesn't take a large amount of either to get a good result so be moderate with it you can always add more later but can't take it out. Fill the two bottles as full as you can with tap water and carefully put it into the water so that the lip of the bottle is turned down, do this with the second bottle. Make about two or three fingers worth of room between the bottom of the bowl and the lip of the bottle and tape it to the side so that the tape is not underwater. If you were unable to get all the air out this is the point where you want to get out that tubing and put it in the bottle while still underwater and suck the air out but try not to get a mouthful of acid or saltwater in your mouth.

If you screw in the bottles' caps when they are full and unscrew them under water in the bowl, you won't have as many air bubbles to worry about...
