Plenty to do at libraries for teens


We usually think of the Delaware County District Library’s summer reading program in terms of young children, but did you know we have some great, fun programs just for teens? Teen librarians Mandy Henning and Becky Woodruff have developed entertaining but educationally sound (just between us!) programs, guaranteed to be enjoyed by Delaware’s teens.

Next Monday and every Monday for the next few weeks at 4 p.m. at the main library, teens are challenged to a head-to-head battle with other teens for the chance to win an awesome gaming prize pack.

Teens can also take the “Hulk Green Foods Challenge” at the main library on Tuesday at 2 p.m., or at the Ostrander branch on Wednesday at 2 p.m.

“Pop Art Creations” will be on deck on Wednesday at 2 p.m. at the Orange branch, where teens learn the basics of pop art and experiment with various techniques in this hands-on program, and then take their creations home. Teens can make and take another art project, working with and learning tips from local artist Cyrus Fire at the main library on Thursday at 2 p.m.

At the Powell branch on Friday at 4 p.m., teens are invited to attend “Teen Robotics with COSI,” where they will use a Lego WeDo robot and discover how to program and complete a series of challenges.

Keep your teens busy this summer at these terrific teen programs. For more information, pick up a copy of “Check It Out!,” the library’s quarterly newsletter, or log on to and click on the “Events” tab.

How do magic erasers work?

According to How It Works, the secret behind these types of erasers is material commonly called melamine foam. With water, melamine foam can remove stains. Melamine foam has been around for about 20 years and has a variety of applications, such as sound insulation and temperature insulation. It is recently that developers realized its potential as a cleaning product. Melamine foam has extremely hard microscopic filaments to remove stains by scraping them off. Apart from being able to scrape stains, the stain removal of these erasers is aided by the fact that the dirt is pulled into the open spaces on the sponge and bound there. These two factors combined make this eraser seem almost magical.

What is the difference between humidity and relative humidity?

The book, Weather Whys, notes that absolute humidity is the measure of water vapor (moisture) in the air, regardless of temperature. It is expressed as grams of moisture per cubic meter of air (g/m3). Relative humidity also measures water vapor but relative to the temperature of the air. It is expressed as the amount of water vapor in the air as a percentage of the total amount that could be held at its current temperature.

Who said, “Of all the sad words of tongue and pen, the saddest are ‘It might have been.’”

The actual quote, credited to poet John Greenleaf Whittier, is, “Of all sad words of tongue or pen, the saddest are these, ‘It might have been.’” It is from his poem “Maud Muller” and is in the last verse of the poem:

Alas for maiden, alas for Judge,

For rich repiner and household drudge!

God pity them both! and pity us all,

Who vainly the dreams of youth recall;

For of all sad words of tongue or pen,

The saddest are these: “It might have been!”

Whittier was born in Massachusetts in 1807 and was an influential American Quaker poet and ardent advocate of the abolition of slavery in the United States. He is usually listed as one of the Fireside Poets. The venerable reference book, Bartlett’s Familiar Quotations, was used to find this answer.
