Heather Inczauskis, from the North Central Regional Library system, visited the Waterville Library on Aug. 16 and delighted children and adults with the “Science of Sound.”

Her Makerspace S.T.E.M. (Science, Technology, Engineering, Math) presentation was an audience participation program using Boomwhackers, bottles, glasses and even “Star Wars” props and music.

Inczauskis showed how many of the sound effects heard in the movies and on TV are made, such as a slinky attached to the bottom of a small bucket makes the sound of the space ships in “Star Wars.”

She also showed how different levels of sound affect how items vibrate. A demonstration involved placing cake decoration sprinkles on top of a speaker and then turning the volume of the sound up and down. The louder the sound the more the sprinkles moved.

Those attending also observed sounds made when blowing into bottles containing various levels of water, and making crystal glasses “ring” by touching around the rim of the glass. Sounds were also made through vibrations in a bowl of water.

After the presentation, the children were able to make their own “sound” instrument using string, plastic cups and plates, and rubber bands.

Waterville librarian Amy Larsen hopes to bring more S.T.E.M. programs to the library throughout the year for children, especially on Fridays when there will be no school. Watch for further details on the Waterville Library Facebook page or call the library at 745-8354.
