Three checks before you trust any water car claim. One, the plates: the right stainless grade in potassium hydroxide, or rust chokes the gas. Two, the bubbler: gas must bubble through water on its way to the engine, so a flashback stops before it reaches the cell. Three, the numbers: fuel use before and after, same road, same conditions. Save this video and run all three checks before you build. Hit the HYPE button if this helped.
