This video demonstrates the volume contraction that occurs when water mixes with alcohol. In the first shot, I pour 150 milliliters of water into a measuring cup. In the second shot, I repeat the same process with 91% isopropyl alcohol. Then, I mix the two and zoom in to show that the total volume is less than 300 milliliters.
I think having the liquids pre-poured and measured out for your video would have enhanced the overall viewing experience. But this is a very cool concept I had not heard of before.
I’d love to have seen the mass of the two liquids separately and then mixed, as a way to quantify things like spillage and unpoured amounts. Great concept, that’s a cool thing to try and show.
I am curious if you pour the alcohol in slowly, would the final volume be close to the 300ml? Perhaps the mixing of the fluids is what causes this volume contraction?

I liked your concept, I think the liquids could’ve been differentiated more, but overall I can see your vision and what you were trying to achieve.
