: [[Scientific Evidence|Evidence]] of the '''particle model''' can be shown by pouring 50[[ml]] 50ml of [[pure]] [[water]] and 50[[ml]] 50ml of [[pure]] [[ethanol]] into a [[Measuring Cylinder|measuring cylinder]]. The [[solution]] is only 97[[ml]] 97ml because [[ethanol]] [[molecule]]s are bigger than [[water]] [[molecule]]s so the [[water]] [[molecule]]s fit between the [[ethanol]] [[molecule]]s like pouring 50[[ml]] 50ml of sand and 50[[ml]] 50ml of marbles into the same container. It will not make 100[[ml]]100ml.
