Two colorless liquids are mixed together and after a few moments the mixture turns a dark blue color. This would be a great &quot;experiment&quot; to show at a family gathering or dinner party. Since the reaction always takes the same amount of time, you know exactly when the clear liquid will change to dark. Imagine walking around with this cup and seconds before it's about to change, you announce to everyone that you'd really like a darker kind of liquid in your cup. Bang! it changes almost on command! Now that would be a cool way to start talking about how a couple of simple chemical reactions are going on at the same time to make this &quot;clock reaction&quot; occur. This version of the classic &quot;iodine clock reaction&quot; uses safe household chemicals that most people have on hand at home. <span class='read-more'><a href="http://sciencecafe.org/content/article/turn-water-wine">&nbsp;read&nbsp;more&nbsp;&raquo;</a></span></p> http://sciencecafe.org/content/article/turn-water-wine#comments Activity Chemistry Halloween halloween hydrogen peroxide magic potion Thu, 17 Jan 2008 19:18:37 -0500 Carl 153 at http://sciencecafe.org/content
