Cut a 2" piece of pipe. Cut 11 more pieces - each 1/2" longer
than the last. For example, the first piece will be 2", the next 2-1/2",
3", 3-1/2", etc. You may need an adult to help with this.
To straighten and clean pipe, soak in hot water for a minute of two.
When pipe has softened, straighten it. Scrub pipe if necessary to remove
Dip in cold water to solidify. Let outside of pipes dry thoroughly.
