| Besides some big words to surprise your friends, in #27 you learned that the farther the tube hung down, the faster the water flowed. Today's word: "activated". The water won't start flowing through the tube by itself because it must be "activated." A swing won't swing unless you push it to activate it. One of the rules of the whole big universe is 
|  What to do: Place a water bucket on the edge of a porch, place a small brick on the end in the bucket. Now make the top part of the syphon go way up high - like over the "#28, above, for a high "mountain" while you are down BELOW the bucket. Now start sucking on the tube until the water gets all the way up to the top, and then starts coming down. You must "work" to get the water "activated". "Activation" would be less if you just draped the tube over the lip of the bucket, right? Next, drape the tube up high again AND then over chairs and railings. Do you have to "work" harder with little mountains and one big one than with only one "mountain"? The work of activation depends only on how high the highest mountain is. When you next ride a real roller coaster, ask yourself why the first "mountain" is the highest.
