Observe how the properties of water turn cornstarch into an imitation of quicksand in this activity. Only cornstarch and water are needed to make an interesting mixture that is actually considered a ‘suspension’ because the cornstarch is finely distributed within the water. Play around with the suspension to see how it reacts to slaps, pokes, or being stirred with a spoon. Be sure to clean up after – this quicksand can get messy!
