3. Anti-siphon to keep vinegar from electrolyser.

4. Vinegar at 1 inch to nuetralize KOH and prevent contamination of fuel cell.

5. Anti-siphon to keep water from entering fuel cell.

6. Water 3 inches (distilled, NEVER TAP) to keep backpressure on fuel cell.

If a hydrogen bottle is used only test tubes 5 and 6 are needed.

If a PEM electrolyser is used test tubes 3 and 4 are not needed, only a single test tube for a water trap is needed. Test tube 1 is filled with water, not vinegar.
