if you add just the right amount of water to cornflour it becomes very thick when you stir it quickly. This happens because the cornflour grains are mixed up and can’t slide over each other due to the lack of water between them. Stirring slowly allows more water between the cornflour grains, letting them slide over each other much easier. Poking it quickly has the same effect, making the substance very hard. If you poke it slowly it doesn’t mix up the mixture in the same way, leaving it runny. It works in much the same way as real quick sand. DO NOT POUR QUICKSAND DOWN THE DRAIN. IT MAY SEPARATE AND BECOME A HARD CLUMP OF CORNSTARCH! Stay tune for more science projects
